Question

Evaluate 7 to the 2 power + 6x - 5 + p when x = 4 and p = 2

Answer 1

To evaluate the expression 7 to the 2nd power + 6x - 5 + p when x = 4 and p = 2, we substitute the values of x and p into the expression and perform the calculations:

7^2 + 6(4) - 5 + 2

First, calculate 7^2:
7^2 = 49

Next, substitute x = 4 and p = 2 into the expression:
49 + 6(4) - 5 + 2

Then, calculate 6(4):
6(4) = 24

49 + 24 - 5 + 2

Finally, perform the addition and subtraction:
49 + 24 - 5 + 2 = 70

Therefore, when x = 4 and p = 2, the expression 7^2 + 6x - 5 + p evaluates to 70.
