Answer:
x²-4x-12
Step-by-step explanation:
multiply each term in the first parentheses by each term in the second parentheses
x*x+2x-6x-6*2
calculate the product
x²+2x-6x-12
collect like terms
x²-4x-12
A. look the point A is (1,1) then B is up 4 and C is over 3
Answer:
11/10
Step-by-step explanation:
The area ratio is the square of the radius ratio (k):
(121/100) = k²
k = √(121/100) = 11/10
The ratio of radii is 11/10.
You can change this into 0.4, which is 4 tenths. 4 tenths translates to 4/10 and you can simplify from there.
2/5 is the final answer as you can divide the numerator and denominator by 2.
