Let length = L m and width = W m. Then:-

LW = 350

2L + 2W = 90

from the above equation:-

L = (90 - 2W) / 2

Substituting for L in the first equation:-

W(90 - 2W) / 2 = 350

90W - 2W^2 = 700

2W^2 - 90W + 700 = 0

(2W - 70)(W - 10) = 0

W = 35 , 10

therefore L = 10, 35

Answer Length = 35m and width = 10 m

Which equation is the inverse of 5 y + 4 = (x + 3) squared + one-half?
8_murik_8 [283]

The inverse of the given function is y = √5x + 7/2 - 3

<h3>Inverse of a function</h3>

Given the function expressed below;

5y + 4 = (x+3)² +1/2

5y = (x+3)² - 7/2

y = 1/5(x+3)² - 7/10

Replace y as x

x = 1/5(y+3)² - 7/10

Make y the subject of the formula

5x = (y+3)²- 7/2

(y+3)² = 5x + 7/2

y+3 = √5x + 7/2

y = √5x + 7/2 - 3

Hence the inverse of the given function is y = √5x + 7/2 - 3
