Answer:
-16-72v
Step-by-step explanation:
-8*2 = -16
-8*9v = -72v
so, -16 + (-72v) -> -16-72v
First we need to find the area of the fence, since paint covers square feet and squared units refers to area. The area of the fence is 26 x 7, which is 182 sq ft. If one gallon of paint will cover 350 sq ft, your proportion will look like this, with gallons of paint on top and square feet on the bottom.

. Cross multiply to get 350x = 182 and x = .52, just a bit over a half of a gallon of paint.
The answer is 6 as if you plug in 6 in the denominator (6)-6 is 0 which makes the fraction undefined
Answer:
for question one - x = 12
Step-by-step explanation:
a triangle is always 180, in other words you will add all the corners equal to 180
ex (for first question) - 7x -2 + 4x + 5x - 10 = 180
you add like terms, the x with x and single numbers with numbers, which results in 16x - 12 = 180. then you do the original operation "what you do to one sign of the equal side you do to the other"
