Which simplified expression represents the area of the parallelogram

The area of a parallelogram is its base times its height.

Step-by-step explanation:

Area is for 2 dimensional shapes. (Shapes with two dimensions in parallelograms they are often referred to as base times height, or length times width). Area is the space inside a two dimensional object, and to find this use the length and the height to find the space in the 2-D figure.

Side note: Volume is "the area of 3 dimensional figures". Three dimensions meaning Length, Width and Height. So there is no area for 3-D figures. (unless you are using Surface Area)

Hope this Helps!

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
