In japan, farmers have created watermelons in the shape of rectangular prisms. find the volume of a prism-shaped watermelon in cubic inches if its length is 10inches, its width is 2/3 foot, and its height is 9 inches.

Step-by-step explanation:

Given: The length of the prism = 10 inches

The height of the prism = 9 inches

The width of the prism =

We know that 1 foot = 12 inches

Then, width of the prism =

The volume of rectangular prism is given by :_

Hence, the volume of a prism-shaped watermelon =

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
