Answer:
2 or 8
Step-by-step explanation:
because 2x2=4 and 4x2=8
A. x = -2 and y = -5
check:
x^2 - 9 = 0
B. x = 0 and y = -6
check:
x^2 - 6 = 0
C. x1 = 3, x2 = 5
check:
(x - 3)(x - 5) = 0
D. x1 = 0, x2 = 4
check:
x(x - 4) = 0
Answer:
(x + 3) × (2x - 7)
Step-by-step explanation:
2x² - x - 21
Write as a difference
2x² + 6x - 7x - 21
Factor the expressions
2x × (x + 3) - 7 (x + 3)
Factor the expression
(x +3) × (2x - 7)
Since there are 2 variables, there won’t be a numerical answer, and since we are solving for g, we have to isolate g.
9g=W
divide 9 from both sides
g=W/9
Your answer is W/9
