A farmer needs to build a goat pen. The pen will be 9 yards wide and 20 yards long. The fencing material costs $8.90 per yard. How much will it cost to buy enough fencing material to build the goat pen?

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)

step-by-step explanation:

you first to choose the points and then move from then as the slope you have
