(7x+2)(20-3x/4) = 140x + 40 - 21x²/4 - 3x/2 = -21/4 x² + 138 1/2 x + 40
this is one of those multiplications that doesn't make the result look any simpler...
Answer:
B. (x+1)^2 + (y-7)^2=196
Step-by-step explanation:
The equation is (x-h)^2 + (y-k)^2=r^2
h=-1,k=7 and r=14
(x-(-1))^2 + (y-7)^2= 14^2
(x+1)^2 + (y-7)^2 = 196
