16^2 is 16•16 so x would equal 256
Answer:
10x-5
Step-by-step explanation:
You subtract 15x-5=10x. Then you do -7+2. The 7 is negative . So it would be -7 plus two. So it would equal -5. So it's 10x-5
g(f(x)) means plug in f(x) for every "x" in g(x).
g(f(x))=(x+4)^2-1=x^2+8x+16-1=x^2+8x+15
answer: x^2+8x+15
C=pi(d)
So d=7ft
Then pi(7ft)=21.98
Multiply first then you would wanna add but you can't until you subtract 5-3 then add I got 12
