Answer:

(9 x - 7 y) (9 x + 7 y)

Step-by-step explanation:

Factor the following:

81 x^2 - 49 y^2

Hint: | Express 81 x^2 - 49 y^2 as a difference of squares.

81 x^2 - 49 y^2 = (9 x)^2 - (7 y)^2:

(9 x)^2 - (7 y)^2

Hint: | Factor the difference of two squares.

Factor the difference of two squares. (9 x)^2 - (7 y)^2 = (9 x - 7 y) (9 x + 7 y):

Answer: (9 x - 7 y) (9 x + 7 y)

A cube, the sides are equal. So 13^3 or 13*13*13 = the volume of the cube. Then work your way to the rectangular prism.

What is the slope intercept form of the linear equation 4x + 2y = 24
castortr0y [4]
The answer is: y = -2x+12

4x+2y=24=

4x-4x+2y=24-4x=

2y=24-4x

Divide each piece by 2=

2y/2=24/2-4x/2

y=12-2x

But, slope intercept form is y=mx + b so you must put the second part in reverse, making the answer to the equation be y=-2x+12
(Don't forget the - on -2)
