Answer:
B. 8 ft
Step-by-step explanation:
The area of the rectangle is ...
A = LW = (16 ft)(4 ft) = 64 ft²
The area of the square in terms of its side length is ...
A = s²
For the square to have the area of the rectangle, its side length must be ...
64 ft² = s²
s = √(64 ft²) = 8 ft
A side of the square is 8 feet long.
Answer:
6 and -4
Step-by-step explanation:
a + b = 2
a - b = 10
Solve:
from the first eq.
a = 2 - b
replacing this value in the second eq.
(2-b) - b = 10
2 - 2b = 10
-2b = 10 - 2
-2b = 8
b = 8/-2
b = -4
from the second eq.
a - b = 10
a - (-4) = 10
a + 4 = 10
a = 10 - 4
a = 6
Check:
from the first eq.
6 + (-4) = 2
6 - 4 = 2
Answer:16y I think
Step-by-step explanation:
Take out the y, 2+5-3 is 4, and to the second power is multiplying 4 twice, so 16. theyre all have the same variable to the right, so 16y
Answer:
