Divide total price by amount bought:
120.96 / 144 = 0.84
It cost $0.84 for 1 square foot.
A= <span>π (n + 4) ^2
= </span><span>π (n + 4) (n + 4)
remember order of operations FOIL
= π (n^2 + 4n + 4n + 16)
= </span>π (n^2 + 8n + 16)
A= πn^2 + 8πn + 16<span>π
do the same for B just change the signs
B = </span>πn^2 - 8πn + 16<span>π
subtract the two
(</span>πn^2 + 8πn + 16π) - (πn^2 - 8πn + 16<span>π)
=16</span><span>πn</span>
Answer:
Additive inverse
Step-by-step explanation:
Every real number has an additive inverse, i.e., for every real number x, there exists a real number y such that
Obviously, y is simply -x.
So, in this case, we can see that 3 and -3 are additive inverse, because they give 0 when summed.
