What is the value of 12 - b^2 given b + -4?
In connexus please help me!!!!
To find the value of 12 - b^2 when given b = -4, we can substitute -4 into the expression for b.
First, let's simplify the expression by replacing b with -4:
12 - (-4)^2
Now, we need to evaluate the exponent (-4)^2. The exponent, which is 2, means that we need to multiply -4 by itself:
(-4)^2 = (-4) x (-4) = 16
Replacing (-4)^2 with 16, we have:
12 - 16
Finally, subtract 16 from 12:
12 - 16 = -4
Therefore, the value of 12 - b^2, when b = -4, is -4.
