Answer:
No
Step-by-step explanation:
No, because the perimeter of a rectangle is 2(x+y). Justin added the sides. Then he should have multiplied by 2 but he didn't so Justin is incorrect.

Answer:
1/2
Step-by-step explanation:
We want to evaluate 16 to the power of 1/2 multiplied by 2 to the power of -3. That is:
![16 ^{1/2} * 2^{-3}](https://tex.z-dn.net/?f=16%20%5E%7B1%2F2%7D%20%2A%202%5E%7B-3%7D)
Simplifying:
=> ![4 * \frac{1}{2^3}](https://tex.z-dn.net/?f=4%20%2A%20%5Cfrac%7B1%7D%7B2%5E3%7D)
![4 * \frac{1}{8} = \frac{1}{2}](https://tex.z-dn.net/?f=4%20%2A%20%5Cfrac%7B1%7D%7B8%7D%20%3D%20%5Cfrac%7B1%7D%7B2%7D)
The answer is 1/2.

Step-by-step explanation:
Answer:In geometry, the parallel postulate, also called Euclid's fifth postulate because it is the fifth postulate in Euclid's Elements, is a distinctive axiom in Euclidean geometry. It states that, in two-dimensional geometry
It must be 21.3 feet.
The sides of the triangle given to us are the side opposite the angle to the ground, 20, and the missing side is the hypotenuse.
opposite/hypotenuse is the ratio for sine:
sin 70 = 20/x
Multiply by x:
x sin 70 = 20
Divide both sides by sin 70:
(x sin 70)/(sin 70) = 20/(sin 70)
x = 21.283 ≈ 21.3
