Answer:
5x
Step-by-step explanation:
since opposite of negative is positive
A^2+b^2=c^2
160^2+160^2 = 51,200
Square root of that is <span>226.27416998</span>
It is 7. None of the other ones fit at all
You just add all the sides together for perimeter
the answer is105
Answer:
Step-by-step explanation:
f(-9+h)= (-9+h)² = h²-18h+81
f(-9+h)-f(-9)=h²-18h+81 -81 because : f(-9) = (-9)² = 81
f(-9+h)-f(-9)=h²-18h
(f(-9+h)-f(-9))/h=(h²-18h)/h = h(h-18)/h =h-18
lim (f(-9+h)-f(-9))/h = lim(h-18= - 18
h→0 h→0
