Given that y varies directly with x, find the equation of direct variation.<br> x is 14 when y is 12
Sergeu [11.5K]

Step-by-step explanation:

x×k = y

14×k = 12

k = 12/14 = 6/7

so, the equation is

x × 6/7 = y

or

y = 6x/7

or

y = 6/7 x

Factor. Look for a GCF first.<br><br> X^3+2x^2-48x
svp [43]

Answer:

x(x - 6)(x + 8)

Step-by-step explanation:

First, the GCF of these 3 terms is x.

So to separate x from this it now becomes x(x^2 + 2x - 48).

Now to factor the expression inside the parentheses easily I use "a" and "b" to make it easier.

a + b = 2 (from 2x)

a * b = -48 (from third term of expression)

a = -6, b = 8

Substitute "a" and "b" and I get: x(x - 6)(x + 8)
