Answer:
x = - 4, x = 2
Step-by-step explanation:
Given
3x² + 6x - 24 = 0 ( divide through by 3 )
x² + 2x - 8 = 0 ← in standard form
(x + 4)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 4 = 0 ⇒ x = - 4
x - 2 = 0 ⇒ x = 2

Answer:
just a and b
Step-by-step explanation:
to solve this, you need to set up an equation to solve for <em>x, </em>the number of square meters waxed in an hour:

you can use cross multiplication to solve for x:


so jessica can wax 100/3 square meters per hour. you can convert this to decimal form (which would be 33.3 repeating) or you can leave it in fraction form.
Answer:
2
Step-by-step explanation:
12x+6=20-10 (subtract 6 to -10)
12x=20x+-16 (subtract 20)
-8=-16 (divide -16 by -8)
x=2
