m = 4, p = 4

Note that when two variables are placed directly next to each other, you are multiplying

plug in 4 for both m and p

(4)(4) + 4

Multiply

4 x 4 = 16

Add

16 + 4 = 20

20 is your answer

Which expression is not equivalent to the other three? 2x 2 2x 3x – 8 4 7x – 2 –2 5x 2x – 4 8x – x – 6.

erik [133]

The expression is not equivalent to $\rm 28x-16$ .

<h2>Polynomial</h2>

An expression of more than two algebraic terms, basically sums of terms and variables of power n.

<h2>Given</h2>

$2x+2 ,\ 2x,\ 3x-8, 4,\ 7x-2,\ -2,\ 5x,\ 2x-4,\ 8x,\ -x-6$

<h2>Step by step explanation</h2>

$\rm Equivalent\ expression = add\ all\ the\ given\ terms.\\
Equivalent\ expression = 2x+2+2x+3x-8+4+7x-2-2+5x+2x-4+8x-x-6\\
Equivalent\ expression = 2x+2x+3x+7x+5x+2x+8x-x+2-8+4-2-2-4-6\\
Equivalent\ expression = 28x-16\\
$

Then the expression is not equivalent to $\rm 28x-16$ .

Thus, the expression is not equivalent to $\rm 28x-16$ .
