Answer:
the answer to this question is -13x + 13
Part A: the area of a rectangle is A= lw, so
A= lw
Height= 6x+3.= 9x
Width= 8
Which makes the expression to this area 9x x 8 ( 9x times 8 )
Part B: you do the same to get the expression here, so the expression would be
6x x 12 ( 6x times 12 )
The answer to this part is yes because both end up being 72x once you get the answer of each.
Answer:
x=1 , y = -1
Step-by-step explanation:
-2.4x-3.6y = 1.2
2.4x+1.2y = 1.2
Add the equations together
-2.4x-3.6y = 1.2
2.4x+1.2y = 1.2
---------------------------
-2.4 y = 2.4
Divide by -2.4
y = -1
Now find x
2.4x +1.2y = 1.2
2.4x +1.2(-1) = 1.2
2.4x -1.2 = 1.2
Add 1.2 to each side
2.4x -1.2+1.2 = 1.2+1.2
2.4x = 2.4
Divide by 2.4
x = 1
