Answer:
Step-by-step explanation:
f(x)=x²-1
f(x-3)=(x-3)²-1
=x²-6x+9-1
=x²-6x+8
It is 4.50+20y=100 bc its y=mx+b
Answer:
a= 20
b= 169.7
c= 29.71
Step-by-step explanation:
The formula of a triangle is (h*b)/2
a= (5*8)/2
b= to find the height, you can use the pythagorean theorem 18^2 - 6^2 = square root of 288. Which is 12root 2 or 16.97. (16.97*20)/2
c= using the pythagorean theorem- 11^2 = 7^2 - c^2 = square root 73, or 6root 2, or 8.49. (8.49* 7)/2
