Tomas factored the polynomial completely. What is true about his final product? 3x4−18x3+9x2−54x Ax(x2+B)(x+C)
iren2701 [21]

Answer:

A and B are both 3.  

Step-by-step explanation:

The given polynomial is 3x^4-18x^3+9x^2-54x.

We factor the GCF to obtain:

3x(x^3-6x^2+3x-18)

We factor further by grouping to get:

3x[x^2(x-6)+3(x-6)]

3x(x^2+3)(x-6)

We compare this to the given factored expression:

3x(x^2+3)(x-6)=Ax(x^2+B)(x+C)

We must have A=3,B=3, C=-6

Which is an equation of the line that is perpendicular to 3x+y=-5 and passes through the point (3, -7)?
nataly862011 [7]

Answer:

y+7=1/3(x-3) in point slope

y=1/3x-8 in slope intercept form

Step-by-step explanation:

First put 3x+y=5 in slope-intercept form (y=mx+b)

y=-3x+5

Give that the slope is -3 the perpendicular slope would be 1/3

now using the points (3.-7)

y+7=1/3(x-3) in point slope

y=1/3x-8 in slope intercept form
