Answer:
216
Step-by-step explanation:
the area is ((B + b) x h) / 2
which is ((22 + 14) x 12) / 2
The markup is 150%
126/84= 1.5
1.5 x 100 = 150%
Proof : 1.5 x 84 =126
Answer:
x = -4
Step-by-step explanation:
So we start with the equation -6x - 7 = -1(-9 + 2x)
Then we distribute the -1 to the -9 and the 2x so we get: -6x - 7 = 9 - 2x
Now we make the x-values on one side and the numbers on the other side like this:
-6x + 6x - 7 - 9 = 9 - 2x + 6x - 9
-16 = 4x
Now we divide 4 / -16 which gives us x = -4
-16/4 = 4x/4
x = -4
