A. First move all to the left side of the equation(Normal form)
x^3 - 49x= 0
B. Factor out an x, which is the GCF (Factored form)
x(x^2 - 49) = 0
C. Find solutions by making each x piece equal to 0. The first part is just x=0 and the second part is just factoring the difference of squares and then solving.
x=0, x^2 - 49 =0
x=0, x + 7 = 0, x - 7 = 0
Therefore, the answers for Part C are:
x = 0, x = -7, x = 7
Answer:
<h2>
y - 2 = -3(x - 1)</h2>
Step-by-step explanation:
The point-slope form of the equation that describes the line with a slope of <em>m</em> that contains the point (x₀, y₀) is: y - y₀ = m(x - x₀)
m = - 3
(1, 2) ⇒ x₀ = 1, y₀ = 2
Therefore:
y - 2 = -3(x - 1)

multiply the parallelogram's height, 7, by it's base, 12. (7 × 12 = 84)
Answer:
6.45
Step-by-step explanation:
6.9-6.0=0.9
0.9÷2=0.45+6=6.45
This is the middle between 18 and 21.
