1. What is the value of 14 – a² given a = -3?
A. 23
B. 11
C. 8
D. 5
14 – a²
14 + (3^2) = 14 + 9 =
To find the value of 14 – a² given a = -3, we substitute the value of a into the expression and perform the calculation.
Step 1: Start with the expression 14 - a².
Step 2: Substitute the value of a, which is -3, into the expression.
14 - (-3)²
Step 3: Simplify the expression within the parentheses, remembering to square -3.
14 - (-3) * (-3)
14 - 9
Step 4: Perform the remaining calculation.
14 - 9 = 5
Therefore, the value of 14 - a², given a = -3, is 5.
