A rectangle has a height of 7 and a width of 2x2 – 3.
Express the area of the entire rectangle.
Expression should be expanded.

A = 14x^2 - 21:  Area of rectangle

Step-by-step explanation:

The area of a rectangle of width W and height H is A = WH.

If H = 7 and W = 2x^2 - 3, then the area of the rectangle is

A = (2x^2 - 3)(7), or

A = 14x^2 - 21:  Area of rectangle

answer: a and c are correct

step-by-step explanation:

the +5 is the vertical translation

the added negative symbol in front is the reflection over the y-axis

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
