What does x equal? What’s the perimeter?

X= 16

Perimeter is 160 meters

Step-by-step explanation:

5(x-12)

5x-60 (Distributive property

Then add the x+4 to the equation

5x-60=x+4

Subtract X from both sides

4x-60=4

Add 60 to both sides

4x=64

Divide both sides by 4 so that you can get X by itself

X=16

Now plug in 16 for x in one of the original equations

(16) + 4 = 20

Each side equals 20 units

Now multiply that number by the number of sides

20 * 8 = 160 meters

26?

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
