By determining the area of the square, we get

Step-by-step explanation:

Step 1:

The area of a square is given by squaring its side length.

The given squares side length is cm.

The area of a square Here a is the side length.

The area of the square is given as 7 cm².

Step 2:

Substituting the value of a in the equation, we get

Taking the x values on one side and the constants on the other side, we get

So

So it has been proved.

answer: no

step-by-step explanation:

you are only given the cost not the amount of pounds.

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.
