Answer

-1,11

step by step

when x =11

3|x-5|=20

3|11-5|+2=20

3|6|+2=20

18+2=20

20=20

when x=-1

3|-1-5|+2=20

3|-6|+2=20(the -6 became 6 due to | | sign)

3*6+2=20

18+2=20

20=20

What is the value of the expression 5x2 + 2x when x = 5?

masha68 [24]

Answer:

135

Step-by-step explanation:

Given:

$x = 5$

To determine a numerical value for the expression, simply substitute the value of "x" into the expression and simplify the expression, if necessary, to determine a specific number for the expression provided.

$\implies 5x^{2} + 2x$

$\implies 5(5)^{2} + 2(5) \longrightarrow \longrightarrow \longrightarrow (x = 5)$

$\implies 5(5)(5) + 2(5)$

$\implies 125 + 10$

$\implies 135$

Therefore, the value of the expression $5x^{2} + 2x$ when x = 5 is 135.
