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).
Answer:
x= -3 or x= -4
Step-by-step explanation:
Answer:
B) It is irrational and equal to 
Step-by-step explanation:
The expression, 
, is an irrational expression because it contains two irrational numbers, 
and 
. Both number are not perfect square. there is no whole number that would be squared that will give you 18 nor 2.
The expression can be equals the following:
Answer:
87
Step-by-step explanation:
earning rate (R) = $5/hr
total (T) = $287
time (t) = 40 hr
tips = T - Rt
= $287 - $5*40
$87
