Answer:

length = 2x = 2(9) = 18 yds

Step-by-step explanation:

Let width = x

Let length = 2x

Area = 162 yd2

length × width = Area

2x(x) = 162

2x2 = 162

Divide by 2 on both sides of equation.

x2 = 81

Square-root both sides of equation to undo the exponent.

x = √(81)

x = 9

Substitute this x value into the initial variables.

width = x = 9 yds

length = 2x = 2(9) = 18 yds

Nesterboy [21]

Answer: The Expression is Equivalent, However, NOT completely factored.

Step-by-step explanation:

3x^2 - 12

Following:

3 ( x^2 - 4 )

Factor:

3x^2 - 12

Factor Out Common Term 3:

3 ( x^2 - 4 ) = 3 (x^2 - 4 )

Factor:

x^2 - 4

( x + 2 ) ( x - 2 )

Answer:

3 ( x + 2) ( x - 2)

Hence, The Expression is Equivalent, However, Wasn't Completely Factored.

Hope that helps!

In Mathematics Geometry,<em> lateral face</em> is said be the side of a 3D-figure in that is not a base.

The faces in in a prism or pyramid which are not bases are basically the lateral faces.

For example, the lateral faces are basically parallelograms in Triangular prism which are not the bases.
