Answer:

Step-by-step explanation:

To solve for ED, create proportion between the two similar triangles.

$\frac{Big Side}{Big Side} =\frac{little side}{little side}$

where Big represents the bigger triangle an little represents the smaller triangle.

$\frac{2x+4}{9}=\frac{x+4}{6}$

Cross multiply and solve for x.

9(x+4)=6(2x+4)

9x+36=12x+24

9x+36-24=12x+24-24

9x+12=12x

9x-9x+12=12x-9x

12=3x

4=x

Lastly substitute the value into ED which is x+4.

4+4=8

SIMPLIFY (x + 5)(2x - 6)<br> A) 2x2 - 30 <br> B) 2x2 - 6x <br> C) 2x2 + 7x - 6 <br> D) 2x2 + 4x - 30

Answer:

D) 2x²+4x-30

Step-by-step explanation:

You would multiply x and 2x; x and -6; 5 and 2x; 5 and -6

(x)(2x) = 2x²

(x)(-6) = -6x

(5)(2x) = 10x

(5)(-6) = -30

Now just put it back in the order that it was listed in the equation starting with (x)(2x)

This would give you 2x²-6x+10x-30

Simplify even further to get 2x²+4x-30

What is an equation of the line that passes through the point (2,−6) and is parallel to the line x−2y=8?

lorasvet [3.4K]

Answer:

y = x/2 - 7

Step-by-step explanation:

First, we need to find the slope of the given equation: x - 2y = 8

Subtract x from both sides

x - 2y = 8

- x - x

-2y = 8 - x

Divide both sides by -2

-2y/-2 = (8 - x)/-2

y = -4 + x/2

The slope of this equation is 1/2

So the equation of our parallel equation is y = x/2 + b

We have to find b, so plug in the given coordinates

-6 = 2/2 + b

-6 = 1 + b

Subtract 1 from both sides

-6 = 1 + b

- 1 - 1

b = -7

Plug it back into the original equation

y = x/2 - 7
