Answer: OPTION A
Step-by-step explanation:
We need to remember that Product of powers property, which states that:
Let's check the options:
A. For 
you can apply the property mentioned before. Then:
(It is the equivalent expression)
B. Add the exponents:
(It is not the equivalent expression)
C. For 
you can apply the property mentioned before. Then:
(It is not the equivalent expression)
D. We know that 
and we maje the addition indicated in this option, we get:
(It is not the equivalent expression)
Since it is a square that means each side is equal.
The perimeter is 24, and since there is four sides we would divide it by four to find the length of each side.
24/4 = 6
Each side is 6.
By looking at the picture, one side of the square, is the length of the radius.
The radius of the square is 6.
The only thing left to do is to find the circumference.
The circumference formulas are:
C =
d
C = 2
r
We can use the first one Diameter x pi (3.14)
To find the diameter we would just multiply the radius by two.
6 x 2 = 12
Diameter = 12
So multiply it by pi
12 x 3.14 = 37.68
or D 12
Answer:
18. g= -3
19. x= -1
20. n= 3
21. p= -1
22. d= -3
23. a= 5
Step-by-step explanation:
how to solve the variable (using 18 as an example)
step 1: simplify both sides of the equation.
20+g+g=14
(g+g)+(20)=14(combine like terms)
2g+20=14
2g+20=14
step 2: subtract 20 from both sides.
2g+20−20=14−20
2g=−6
step 3: divide both sides by 2.
2g/2 = -6/2
