The area of a parallelogram is 44.4 square feet and its height is 7.4 feet. what is the length of the base? do not round your answer.

The length of base is 6 feet.

Step-by-step explanation:

Given : The area of a parallelogram is 44.4 square feet and its height is 7.4 feet.

We have to find the length of the base of parallelogram.

Consider the given parallelogram

Area = 44.4 ft²

and height = 7.4 ft

Area of parallelogram = base × height

Substitute, we  have,

44.4 = 7.4 × base

Divide both side by 7.4 , we have,

base = 6 ft

Thus, The length of base is 6 feet.

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
