Question

7 d^2 +10 when d = 3

Answer 1

Hey. Let me help you out

First, let's rewrite the equation in order to minimize confusion. The way you wrote it makes it hard to vision it.

$7d^2+10d=3$

Now, we just replace the variable d with a value we have.

$7(3^2)+10$

Three to the power of two is going to equal to 9.

$7*9+10$

Seven times nine is 63.

$63+10$

Finally, 63 plus 10 is going to be 73.

Answer is 73
