To evaluate the expression 7^2 + 6x - 5 + p when x = 4 and p = 2, we substitute the values of x and p into the expression:
7^2 + 6(4) - 5 + 2
7^2 is equal to 49, 6 times 4 is equal to 24, and adding all the remaining terms, we get:
49 + 24 - 5 + 2
Now, we can combine like terms:
= 73 - 5 + 2
= 68 + 2
= 70
Therefore, when x = 4 and p = 2, the expression 7^2 + 6x - 5 + p evaluates to 70.
