Answer:

x = 9b/C

Step-by-step explanation:

Cx – 4b = 5b

Add 4b to each side

Cx – 4b+4b = 5b+4b

Cx = 9b

Divide by C

Cx/C = 9b/C

x = 9b/C

Vlada [557]

Answer:

A) l = w + 900

B) l * w = 4,000,000

B) l = 4,000,000 / w putting this into A)

A) 4,000,000 / w = w + 900

A) 4,000,000 = w^2 +900 w

A) w^2 +900 w - 4,000,000

Solving by quadratic formula

width = 1,600 length = 2,500

Double-Check

1,600 * 2,500 = 4,000,000

Length = width + 900

2,500 = 1,600 + 900
