Answer:
(16,20)
Step-by-step explanation:
For a dilation about the origin, you just take your scale factor and multiply it to both the points.
A means an area
s side of the square, because of all sides are equal
then Area=s*s or Area=s²
so
A=9*9=81yd²
(2,3) I think. I'm not in Algebra 1, so yeah
(f+g)(x)=0
f (x) + g (x)=0
now,
substitute their values
x^2 -4x + x -18 = 0
x^2 -3x -18 =0
x^2 - 6x + 3x - 18 =0
x (x-6) + 3 (x-6) = 0
(x-6)(x+3) = 0
we have to find it's zeroes (or roots) now:
x-6 =0
x = 6
x +3 =0
x = -3
