Answer:
if a·b=0, then either a=0 or b=0, or both
Step-by-step explanation:
just answered it on apex :)
Answer:
(x-3)(x^2-7) = x^3 -3x^2 -7x + 21
just change the sign of the root and put x in front of it, then multiply the factors all together
(x-3)(x-sqr7)(x+sqr7) roots come in conjugate pairs to eliminate irrational coefficients
(x-sqr7)(x+sqr7) = x^2-7. similar to (a-b)(a+b) = a^2-b^2
Step-by-step explanation:
I would say choice C with 4 is the right ones
Slope is 2 and y-intercept is 9
Answer:
B)Division
Step-by-step explanation:
3x=9
divide both side by 3 gives you
x=3
