Answer:
P = 5x + 11
Step-by-step explanation:
Let x = bottom of triangle
Let 2 + 3x = another side
Let x + 9 = third side
P = x + x + 9 + 2 + 3x
P = 5x + 11
2(\frac{Area}{h} ) - b1 = b2
Step-by-step explanation:
The formula for calculating the area of a trapezoid is the following.
Area = \frac{b1+b2}{2} * h
What we are asked to find is the formula for finding b2. We can do this by rearranging the Area formula and getting b2 by itself on one side.
Area = \frac{b1+b2}{2} * h
\frac{Area}{h} = \frac{b1+b2}{2} .....divide h on both sides
2(\frac{Area}{h}) = b1+b2 .... multiply 2 on both sides
2(\frac{Area}{h} ) - b1 = b2 ....subtract b1 on both sides
Now we have b2 by itself on one side and the formula is rewritten to solve for b2.

Answer:
The width of the rectangular prism is 9 cm.
Step-by-step explanation:
From the formula of the volume of a bar 
we see that 
cm.
Isolate the m, go backwards for PEMDAS.
C = 2m + d
C (-d) = 2m + d (-d)
C - d = 2m
(C - d)/2 = 2m/2
m = (C - d)/2
m = (C - d)/2 is your answer
hope this helps
