6 0

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.

i hope it will help you!
