How many inches of fence will be needed to fence the parallelogram-shaped 198.3 inches by 87.4 inches

Sides of parallelogram are = 198.30 inches and 87.4 inches

To know the length of fence needed to fence the parallelogram, we will find the perimeter of the parallelogram.

Perimeter = 2(a+b) where a and b are the sides of the parallelogram

P=571.40 inches

Hence, 571.40 inches of fence is needed.

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
