Answer:
-8
Step-by-step explanation:
slope is change in y divided by change in x
slope = (12-36)/(11-8)
slope = -24/3
slope = -8
Divide 81 by 9 to get the area of the pantry which is 9 so the other side of the pantry is 3 because 3 times 3 is 9.
Get rid of brackets:
21x +6 +8x
Put 6 to the other side:
21x +8x = -6
27x = -6
Divide both sides by 27
X= -0.22
I think the answer is this
2x-4x+1=0
Combine like terms
-2x+1=0
Subtract 1 both sides
-2x=-1
Divide by -2 both sides
x=-1/2
I really need points so I can answer questions I know the answer to so ima take a guess and say 134
