Ratio of the radii = sqrt16 / sqrt81 = 4/9
so radius of circle Q is found by solving 4/9 = 8/x where x = radius of Q
x = 2*9 = 18
radius of circle Q = 18.
Answer:
(x-7) (x+1)
Step-by-step explanation:
x^2 - 6x - 7
What two numbers multiply to -7 and add to -6
-7*1 = -7
-7+1 = -6
(x-7) (x+1)
Answer:
(x+8) ^2=64
