Question

Evaluate 14 + 3p^2 - 5c for p = 5 and c = 10.

A) 14
B) 89
C) 69
D) 36

Answer 1

When evaluating the expression 14 + 3p^2 - 5c with p = 5 and c = 10, the result is 39.

Step-by-step explanation:

To evaluate the expression 14 + 3p^2 - 5c for p = 5 and c = 10, we need to substitute the values of p and c into the expression:

First, calculate the term 3p^2 using p = 5:

3 × (5)^2 = 3 × 25 = 75

Next, calculate the term -5c using c = 10:

-5 × 10 = -50

Now, substitute these values into the expression and combine them with the constant 14:

14 + 75 - 50

Finally, add and subtract the numbers to find the result:

14 + 75 = 89

89 - 50 = 39

Therefore, the value of the expression when p = 5 and c = 10 is 39.
