Can someone help me with this? I'm confused with how to do it :( If someone could help it would be awesome!!!

I think...

Triangle 2- the perimeter is 22.

Step-by-step explanation:

For perimeter you add all the sides together.

I think for the larger triangle X=4. Because on the 6 side is 4 on the smaller triangle and the 12 side is 8 on the smaller triangle.

So...

6+12+4= 22.

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
