The statement that justifies that ΔBAE ≅ Δ DAE is Side-Side-Angle Postulate. The best option from the statements given is "Classify A triangle". That is definition of a triangle.
What is the Side-Side- Angle Postulate?The Side Side Angle Postulate states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.
Between both triangles, here are the congruent sides and angles:
AB ≅ AD - Given
AE = EA - Reflexive Property. Note that AE is shared by both triangles so we have Two congruent sides.
AC ⊥ BD - that means ∠AEB = ∠AED = ∠BEC = ∠CED = 90°
(perpendicular bisector theorem)
A perpendicular bisector is a line segment that cuts another line segment at 90 degrees. A perpendicular bisector, in other terms, meets another line segment at 90° and splits it into two equal halves.

Given the supply curve below, how many AirPods would Apple produce at a price of $185?
Supply Curve for Airpods- Qs = 6700 + 75P
O 25600
6775
O20575
6960
The given supply curve is: Qs = 6700 + 75P
To find how many AirPods Apple would produce at a price of $185, we can substitute P = $185 in the equation and find the corresponding quantity (Qs).
Qs = 6700 + 75P Qs = 6700 + 75($185) Qs = 6700 + 13875 Qs = 20575
Therefore, at a price of $185, Apple would produce 20,575 AirPods according to the given supply curve.
If f(1) = 0, what are all the roots of the function f (x) = x cubed + 3 x squared minus x minus 3? Use the Remainder Theorem.
The roots of the cubic function:
f(x)= x³ + 3x² - x - 3
are x = 1, x= -1, x = -3
How to find the roots of the function?We want to find the roots of the function:
f(x)= x³ + 3x² - x - 3
We know that x = 1 is a root, because f(1) = 0.
Then we can write that function as:
(x - 1)*(x - a)*(x - b)
Where a and b are the other two roots, then we need to solve:
x³ + 3x² - x - 3 = (x - 1)*(x - a)*(x - b)
Expanding the right side, we will get:
x³ + 3x² - x - 3 = x³ + (-a - b - 1)x² + (a + b + ab)x + (-ab)
Comparing like terms, we can see that:
(-a - b - 1) = 3
(a + b + ab) = -1
(-ab) = -3
The third equation gives:
ab = 3
Replacing that in the second one we get:
a + b + 3 = -1
a + b = - 1 - 3 = -4
a + b = -4
a = -4 - b
Replacing that in the relation above:
ab = 3
(-4 - b)*b = 3
-4b - b² = 3
b² + 4b + 3 = 0
The zeros of that function are:
[tex]b = \frac{-4 \pm \sqrt{4^2 -4*3*1} }{2*1} \\\\b = \frac{-4 \pm 2}{2}[/tex]
Then if b is the value when we take the positive sign:
b = (-4 + 2)/2 = -1
the value of a is:
a = -4 - b = -4 + 1 = -3
These are the other two roots.

People use self-warming and self-cooling devices for many purposes such as keeping drinks cold or food warm. Medical professionals also use these types of devices to store medicines and other substances that need to stay colder than room temperature. These cooling and warming devices use a chemical reaction to produce their chilling and warming effects. Compounds combine in endothermic (heat absorbing) or exothermic (heat releasing) reactions within these devices to help them keep items cool or warm.
Jacob and Natalie are asked by their science teacher to design a warming or cooling device. They decide to design a cold pack that can be used to help keep food cool. Jacob

I 10. The sides of a square are increased by a scale factor of 3. The area of the larger square is what percent of tne area of the smaller square?
The area of the larger square is 900% of the area of the smaller square.
Let's assume that the side of the smaller square is "s". Therefore, the area of the smaller square will be:
Area of smaller square = s²
Now, the sides of the square are increased by a scale factor of 3, which means that the new side length of the larger square will be 3s. The area of the larger square will be:
Area of larger square = (3s)² = 9s²
To find the percentage of the larger square with respect to the smaller square, we need to divide the area of the larger square by the area of the smaller square, and then multiply by 100:
(9s²/s²) x 100 = 900%
This means that the larger square is 9 times the area of the smaller square.

jureks brother is 6 years older than him .Together they are 22 years old ,how old are the brothers.Write down the correct equation?
Answer:
Jurek is 8. His brother is 14
Step-by-step explanation:
let's call Jurek J, and let's call his brother B.
his brother is 6 years older than Jurek.
So, B = J + 6.
B + J = 22
(J + 6) + J = 22
2J + 6 = 22
2J = 16
J = 8
so Jurek is 8
B + J = 22, B = 22 - J = 22 - 8 = 14.

What is the sum of the interior angles of the polygon shown below?
1260° is the sum of all interior angles of the given polygon.
Generally speaking, the measure of the angle at the center of a regular polygon is equal to 360 degrees.
The sum of the interior angles in a polygon can be calculated using the formula:
Sum of interior angles = (n - 2) * 180 degrees
In this formula, "n" represents the number of sides or vertices of the polygon.
In the given problem the number of sides is 9.
Thus,
Sum of all interior angle = (9-2)*180

A rectangular prism with a square base has a height of 17.2 cm and a volume of 24.768 cm² What is the side length of its base?
If rectangular prism with a square base has a height of 17.2 cm and a volume of 24.768 cm², the side length of the square base is 1.2 cm.
Let's denote the side length of the square base as x cm. Then, the volume of the rectangular prism can be expressed as V = x² * 17.2 cm³, and its surface area can be expressed as S = 2x² + 4x * 17.2 cm².
We are given that the volume of the rectangular prism is 24.768 cm³, so we can write the equation:
x² * 17.2 cm³ = 24.768 cm³
Simplifying this equation, we get:
x² = 24.768 cm³ / 17.2 cm² = 1.44 cm²

The equation that could be used to represent the whole pizza is 4/8 + 2/8 = 6/8 = 3/4.
We are given that;
Pizza ate by children= 4/8
Pizza ate by Jonus= 2/8
Now,
4/8 + 2/8 + x = 1
where x is the fraction of the pizza that was saved for later. This equation shows that the sum of the fractions of the pizza that were eaten and saved is equal to 1, which represents the whole pizza. To solve for x, we can simplify the fractions and subtract them from both sides:
4/8 + 2/8 = 6/8 = 3/4
3/4 + x = 1
x = 1 - 3/4
x = 1/4
Therefore, the equation will be 4/8 + 2/8 = 6/8 = 3/4

Answer:
96 cubic inches
Step-by-step explanation:
To calculate the empty space that will be left in the box once the book is inside, we need to find the difference between the volume of the box and the volume of the book.
Volume of the box:
20" x 12" x 2 1/2" = 600 cubic inches
Volume of the book:
18" x 3 1/2" x 8" = 504 cubic inches
Empty space in the box:
600 cubic inches - 504 cubic inches = 96 cubic inches
Therefore, there will be 96 cubic inches of empty space left in the box once Kylie puts the book inside.

How to simplify the expression?
Remember that when we have the quotient of two powers with the same base (like in this case, where the base is 2) the outcome will be a power of the same base, such that the exponent is equal to the difference between the other two exponents.
The rule is:
[tex]\frac{x^m}{x^n} = x^{m - n}[/tex]
Then we can use that to simplify the expression, we will get:
