Answer:
x = -7 or x = 2/3
Step-by-step explanation:
I'm assuming you meant solve for x when f(x) = 0.
f(x) = 3x(x + 7) - 2(x + 7)
0 = (x + 7)(3x - 2) -- Both terms have a common factor of (x + 7) so we can group them
x + 7 = 0 or 3x - 2 = 0 -- Use ZPP
x = -7 or x = 2/3 -- Solve
Answer: 20
Step-by-step explanation: how i got the answer was to multiply everything by two. then add everything together.
Answer:
Correct answer: (a - 4) · (a + 6)
Step-by-step explanation:
Given:
a² - 4a - 24 + 6a = a² - 4a + 6a - 24 = a (a - 4) + 6 (a - 4) = (a - 4) · (a + 6)
God is with you!!!
First hour: 3 = 3¹
Second hour: (3) x 3 = 3²
Third hour: (3 x 3) x 3 = 3³
Fourth hour: (3 x 3 x 3) x 3 = 3⁴
Do you see the pattern? <em>
where n is the number of hours</em>
Answer: 3³,
