all we can really cancel is one of the (x-5) and the "x", is all.
I think you mean how many thousands equal 20 hundreds. Well it's simple, 20 hundreds equal 20*100 which equals 2,000. Therefore, 20 hundreds equals 2 thousands.
Answer:
49 years old.
Step-by-step explanation:
By proportion 7/6 = M/42 where M is Michael's age.
6M = 7 * 42
M = (7*42) / 6
M = 7 *7
= 49.
F(x) = (x² - 3x - 10)(x + 4) becomes (x - 5)(x + 2)(x + 4) when completely factored. Now set each binomial equal to zero.
x - 5 = 0
x = 5
x + 2 = 0
x = - 2
x + 4 = 0
x = - 4
Your zeros are at x = - 4, - 2, and 5. Or at (- 4, 0), (- 2, 0), and (5, 0).
