Step-by-step explanation:
The applicable properties of exponents are ...
(a^b)^c = a^(bc)
(a^b)(a^c) = a^(b+c)
(a^b)/(a^c) = a^(b-c)

That is, since the outside exponent is even, the sign is immaterial. This is also true for the other expression containing -2. The result is positive.

Answer:
1.) Triangle ABC is congruent to triangle DCB
Step-by-step explanation:
For the first one, the first 3 steps proved that all 3 sides in the 2 triangles formed by the diagonal are congruent to each other, meaning triangle ABC is congruent to triangle DCB (I named it like that specifically because the way you name the triangles has to be the exact same way you named the other triangle).
For the second one, the congruency statement should be GL ≅ AD, because the HL congruence theorem states that if a hypotenuse and leg of one right triangle is congruent to the hypotenuse and leg of another right triangle, those triangles are congruent.
Answer:
choice 4) Triangle ABC is congruent to triangle DCB because of the Side-Side-Side theorem

A middle school student reads 48 books in 31/3 years. Find the students reading rate in books per year
Answer: 14 2/5 books per year
Step-by-step explanation:
From the question, we are informed that a middle school student reads 48 books in 31/3 years. The students reading rate in books per year will be calculated as:
= Total books read / Number of years
= 48 ÷ 3 1/3
= 48 ÷ 10/3
= 48 × 3/10
= 144/10
= 14 2/5 books per year

Brian bought 215 pounds of strawberries. In the afternoon his brother ate 56 of the strawberries. How many pounds of strawberries did his brother eat?
Hi there!
Step By Step:
We know that 215 pounds are about 215 strawberries since every strawberry are about 1 pound.
Let think about this... 215 pounds are 215 strawberries.
If his brother ate 56 of the strawberries, it means that his brother ate 56 pounds of the strawberry.
We can also think like this... 56/215
Final Result: 56 pound sof strawberries.

A rectangle has length of 80cm and a width 50cm. And a scale factor of 3.5 what is the area in square cm of the dilated rectangle
Answer:
49,000 square cm
Step-by-step explanation:
To get the area of the dilated rectangle, we need the dilated dimensions
We simply multiply the scale factor by the dimensions
we have this as;
3.5 * 50 = 175 cm
and
3.5 * 80 = 280 cm
The area of the dilated rectangle is thus;
280 * 175 = 49,000 cm^2
Factor.

Tickets for the karaoke talent show sponsored by the Speech Club were priced at $3 for adults and $2 for students. The club treasurer counted 300 tickets sold for a total of $650. Write and solve a system of equations to determine how many adult and student tickets were sold.
Answer:
50 adults and 250 students tickets were sold
Step-by-step explanation:
Given data
Let the number of adults be x and students be y
3x+2y=650------1
x+y= 300---------2
from 2
x= 300-y
put the value of x in 1
3(300-y)+2y= 650
900-3y+2y= 650
900-y= 650
900-650= y
y=250
put the value of y in 2
x+250= 300
x= 300-250
x= 50
Hence 50 adults and 250 students tickets were sold

Two more than 11 times a number is equal to 24. What is the number?
Answer:
2
Step-by-step explanation:
Brainliest?!?!?!?
The answer to this would be 2.
Step by Step Explanation
Equation: 11x+2=24
Variable for the missing number: x
To do this, I suggest writing out an equation with the variable X to represent the missing number that we are trying to find. The equation would look something like this: 11x+2=24.
From here, to solve the equation, subtract 2 from both sides, which would then get the equation to be 11x=22. From here, you would then divide both sides by 11 to get the variable on it's own, which would be x=2. Since x is the variable that we are using to represent the missing number, the missing number would be 2.

Answer:
BODMAS rule
Step-by-step explanation:
There are four basic rules in mathematics, Addition, subtraction, Multiplication and Division. All these operations can be used together or separately depending on the problem. When all the operation are required in the problem then BODMAS rule is applied to simplify the problem. BODMAS rule determines that operation will be performed according to the rule : Division, Multiplication, Addition and Subtraction. First operation which will be performed is division and last will be subtraction. This rule is same for all types of problems.
