Answer:

2(2x+5) (x+1) = 2(x+1)(2x+5)

Step-by-step explanation:

4x^2 +14x+10

Factor out the 2

2(2x^2 +7x+5)

2(2x+5) (x+1)

You need to keep the 2 that you factored out

2(2x+5) (x+1) = 2(x+1)(2x+5) by the Commutative Property of Multiplication

Find the slope of the line please help

Ne4ueva [31]

Answer:

Step-by-step explanation:

Plug 2 points into the equation y2-y1/x2-x1. In this case, I picked (0,-1) and (1,-1). This will make the equation -1--1/1-0. Simplify this to get 0/1 which is equal to 0. Therefore, the slope is 0.

Answer:

$15$

Step-by-step explanation:

Equilateral triangles have equal sides.

Two sides are equal, so we can put up an equation to solve for $x$ .

$6x+3=10x-5$

$6x-10x=-5-3$

$-4x=-8$

$4x=8$

$4x/4=8/4$

$x=2$

Let's solve for one side of the triangle.

$10(2)-5$

$20-5$

$=15$
