Question

I need help with this ... I don't get it

Answer 1

1. The volume is comprise of a cube and prism

V = ( x + 2) ( 2x + 4) + ( x + 2)^2

Solve for x

X = 10.12

2. 1050 = (2x – 4) ( 3x) 5

1050 = (2x – 4) 15x

1050 = 30x^2 – 60x

Solve for x

X = 7

3. 148 = ( x – 5) ( x – 6 ) ( x – 4)

Solve for x

X = 10.35

4. 144pi = pix^2(21)

X = 2.62
