Answer: x = 9</h3>
=========================================
The diagram shows:
Recall that the area of a parallelogram is equal to the base times height
area = base*height
We're told that the area is 117 square units, so that means 13x = 117.
Divide both sides by 13 to isolate x
13x = 117
13x/13 = 117/13
x = 9
The height of the parallelogram is 9
Note how:
area = base*height = 13*x = 13*9 = 117
which helps confirm we have the correct height value for x.
The variable Z is directly proportional to X
Z = kX (Where k is the constant of proportionality)
To find k
54 = k3
k = 54/3
k = 18
now find new Z
Z = 18X
Z = 18(12)
Z = 216
Answer:
12/15 and 24/30 are equivalent fractions
this is the quadratic formula
