Answer:
B
Step-by-step explanation:
no need to explain
hope it helps
Let the width be x, then the length is 2x
2(x + 4 + 2x + 4) = 46
(3x + 8) = 46/2 = 23
3x = 23 - 8 = 15
x = 15/3 = 5 ft
Therefore, width is 5 feet and length is 2(5) = 10 feet
Answer:
A
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y =
( multiply both sides by x³ )
x³y = 19 ( divide both sides by y )
x³ =
( take the cube root of both sides )
x = ![\sqrt[3]{\frac{19}{y} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Cfrac%7B19%7D%7By%7D%20%7D)
Change y back into terms of x, then
(x) =
=
→ A
