(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
Answer:
Divide each side by 2 to isolate x
Step-by-step explanation:
2x = 10
Divide each side by 2 to isolate x
2x/2 = 10/2
x = 5
The answer is (4) because you multiply the like terms in the equation. 5*7=35 and 3i*2i=6i.
Answer is (4)
Answer:
V = 235.5
Step-by-step explanation:
V=π r^2 h
V = pi 5^2 3
V = pi 25 3
V = 3.14 * 75
V = 235.5
