Question

What is the value of 7x 2squared + 2x when x = 3?

Answer 1

Answer:

Given expression has the value 69

Step-by-step explanation:

Given equation is:

$=7x^2 + 2x$

Now we have to put x = 3

So the equation will become:

$=7(3)^2 + 2(3)$

By simplifying:

As $3^{2} = 9$

and 2*3 = 6

So the above equation will become:

$=7(9 ) + 6\\= 63 + 6\\= 69$

So the value of given expression is 69.
