Answer: *x squred +3x-10*
Step-by-step explanation:
(x+5)(x-2)
x squred-2x+5x-10
x squred +3x-10
The equation ( x + 5 ) ( x - 2 ) can be simplified as x² + 3x - 10
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be = A
Now , the equation A = ( x + 5 ) ( x - 2 )
On simplifying the equation , we get
A = x ( x - 2 ) + 5 ( x - 2 )
Expanding the brackets , we get
A = x² - 2x + 5x - 10
On simplifying the equation , we get
A = x² + 3x - 10
Therefore , the value of A is x² + 3x - 10
Hence , The equation ( x + 5 ) ( x - 2 ) can be simplified as x² + 3x - 10

Answer:
A. The perimeter of the third triangle will be equal to the perimeter of the second triangle because the lengths of line segments are preserved during translations.
Step-by-step explanation:
When a shape is translated, it simply means it is moved. Nothing about it is being changed besides the location. Therefore, it will have the same perimeter because its sides are the exact same.

Find the volume of a pyramid with a square base, where the perimeter of the base is 6.9 cm and the height of the pyramid is 2.8 cm. Round your answer to the nearest tenth of a cubic centimeter.
Answer:
V=2.8cm^3
Step-by-step explanation:
The volume of a pyramid with a square base should be considered as the 2.8 cubic centimeter.
Calculation of the pyramid:Since
perimeter of the base is 6.9 cm and the height of the pyramid is 2.8 cm.
So, here
we know that
volume of a pyramid = [tex]1/3(length * width * height)[/tex]
And,
perimeter of a square = [tex]4 * length[/tex]
6.9 = 4 x length
So,
length = 1.725
Now the volume is
[tex]= 1/3 * (1.725 * 1.725 * 2.8)[/tex]
= 2.8

State whether 2.5 + π is rational or irrational. Explain.
Answer: 2.5 + π is an irrational number.
Step-by-step explanation:
Irrational numbers are numbers that can not be written as the quotient of two integer numbers, and they have an infinite number of digits after the decimal point (such that there is not periodicity in these digits).
So suppose that we have an irrational number and we add 1, then the infinite digits after the decimal point will still be there, so the sum will be also an irrational number.
The same can be seen for the sum between an irrational number and a rational number, where the infinite number of decimals after the decimal point will still be there (because the rational numbers have a finite or infinite but periodical decimals after the decimal point), so the sum between an irrational number and a rational number is always irrational.
In this case, we have the addition:
2.5 + π
Which is the sum of a rational number and an irrational number, so we can conclude that this is an irrational number.
Given the kite below, if NO = 5 and OM = 12, what is the value of NM?
Answer:
NM = 13
Step-by-step explanation:
pythagorean theorem: [tex]a^{2} + b^{2} = c^{2}[/tex]
a or NO = 5
b or OM = 12
c or NM = ?
plug in what is known:
⇒ [tex]5^{2} + 12^{2} = c^{2}[/tex]
⇒ [tex]25 + 144 = c^{2}[/tex]
⇒ 169 = [tex]c^{2}[/tex]
square root each side of the equation:
⇒ [tex]\sqrt{169} = \sqrt{c^{2} }[/tex]
solve:
⇒ 13 = c

Given:
AD is an angle bisector in triangle ABC. [tex]m\angle CAB=44^\circ, m\angle ACB=72^\circ, m\angle ABC=64^\circ[/tex].
To find:
The value of [tex]m\angle ADC[/tex].
Solution:
AD is an angle bisector in triangle ABC.
[tex]m\angle CAD=m\angle BAD=\dfrac{m\angle CAB}{2}[/tex]
[tex]m\angle CAD=m\angle BAD=\dfrac{44^\circ}{2}[/tex]
[tex]m\angle CAD=m\angle BAD=22^\circ[/tex]
According to the angle sum property, the sum of all interior angles of a triangle is 180 degrees.
Using angle sum property in triangle CAD, we get
[tex]m\angle CAD+m\angle ADC+m\angle ACB=180^\circ[/tex]
[tex]22^\circ+m\angle ADC+72^\circ=180^\circ[/tex]
[tex]m\angle ADC+94^\circ=180^\circ[/tex]
[tex]m\angle ADC=180^\circ-94^\circ[/tex]
[tex]m\angle ADC=86^\circ[/tex]
Therefore, the angle of angle ADC is [tex]86^\circ[/tex].
