Let x = 6. what is the value of the expression 5x to the 2nd power +x−7 ?

149

Step-by-step explanation:

5 to the second power is 25, because you do 5x5. Then you multiply 25 by x, which is 6, and get 150. Then you add 6 to 150, which is 156, and subtract seven. Also the answer is 149.

The answer is 149

The equation is

5x² + X -7

Putting X as 6 we get

=5(6)²+6−7

=(5)(36)+6−7

=180+6−7

=186−7

=179

true

step-by-step explanation:

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.
