STEP-BY-STEP SOLUTION:

= a^3 - 4a^2 + 12 - 3a

= a^2 ( a - 4 ) + 3 ( 4 - a )

= a^2 ( a - 4 ) - 3 ( a - 4 )

= ( a - 4 ) ( a^2 - 3 )

a^3-4a^2+12-3a=(a^3-4a^2)-(3a-12)\\\\=a^2(a-4)-3(a-4)=\boxed{(a-4)(a^2-3)}\\\\=(a-4)(a^2-(\sqrt3)^2)\\\\\text{use}\ a^2-b^2=(a-b)(a+b)\\\\=\boxed{(a-4)(a-\sqrt3)(a+\sqrt3)}

J^2 over 2j times 2j over 3g
Serhud [2]

Answer:

D

Step-by-step explanation:

given \frac{j^2}{2j} × \frac{2j}{3g}

the 2j on the denominator of the first fraction cancels with the 2j on the numerator of the second fraction, leaving the expression in simplified form as

= \frac{j^2}{3g} → D

What is an equation of the line that passes through the point (-7,-6)(−7,−6) and is parallel to the line x-y=7x−y=7?
kotykmax [81]

Answer:

y = x + 1

Step-by-step explanation:

The gradient of a line can be defined by the equation:

m (gradient) = (y1 – y2 ) ÷ (x1 – x2) ----> "1" and "2" should be in subscript

For (-7,-6) we use x2 and y2 (because this point can be anywhere along a line):

x2 = -7, y2 = -6

Plug these values into the formula above:

m = (y-(-6)) ÷ (x-(-7))

m = (y+6) ÷ (x+7)

At this stage, the equation can't be solved as there are two unknowns. Therefore, the gradient must be found another way. Two lines are parallel if they have the same gradient - in their y=mx+c equations, m will be equal.

x - y=7 is the line alluded to in the question. Rearranging this equation into the line equation format gives:

y = x-7 ---> The gradient (coefficient of x) is 1.

Therefore, the gradient of the other parallel line must also be 1.

This can be substituted into the previous equation to give:

1 = (y+6)÷(x+7)

x+7 = y+6

x+1 = y

Therefore, the answer is y=x+1
