Factor completely<br> (X^2 + x - 6) (2x^2 + 4x) =

Vikki [24]

Answer:

= 2x^4 + 6x^3 - 8x^2 + 24x

= 2x ( 2x^3 + 3x^2 - 4x + 12)

Step-by-step explanation:

(X^2 + x - 6) (2x^2 + 4x) =

Let's open the brackets carefully

x^2 * 2x^2 + x^2*4x + x*2x^2 + x*4x - 6*2x^2 - 24x

= 2x^4 + 4x^3 + 2x^3 + 4x^2 - 12x + 24x

= 2x^4 + 6x^3 - 8x^2 + 24x

= 2x ( 2x^3 + 3x^2 - 4x + 12)

What are the coordinates of the point on the directed line segment from (4, -3)(4,−3) to (9, -8)(9,−8) that partitions the segme

jekas [21]

Answer:

(7, -6)

Step-by-step explanation:

You want to find point X on the segment from A to B such that ...

(X -A)/(B -X) = 3/2

2(X -A) = 3(B -X) . . . . . . cross multiply

2X -2A = 3B -3X . . . . . eliminate parentheses

5X = 2A +3B . . . . . . . . add 3X +2A

X = (2A +3B)/5 . . . . . . . divide by 5

Filling in the given points for A and B, we have ...

X = (2(4, -3) +3(9, -8))/5 = (8+27, -6-24)/5 = (35, -30)/5

X = (7, -6)

The point that divides the segment in the proportions 3:2 is (7, -6).

A=1/2bh solve for b.

melamori03 [73]

Answer:

2A /h = b

Step-by-step explanation:

A=1/2bh

Multiply each side by 2

2A = 2*1/2bh

2A = bh

Divide each side by h

2A/h = bh/h

2A /h = b
