Question

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

Answer 1

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.
