The dimensions of a rectangular prism are multiplied by 1/2 (so the sides of the new rectangular prism will all be half). Describe the effect of change on the volume.

a
The volume will be multiplied by 1/8, 1/8 times as large.

b
The volume will be 1/2 as much.

c
The volume will be multiplied by 1/4, 1/4 times as large.

d
The volume will be twice as large.

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
