A parallelogram by definition is a four-sided figure with opposite sides that are parallel.

If that's the case, the length of opposite sides should be the same as well, meaning that:

AB=CD

then,

\begin{gathered} 3x=x+10 \\ \text{solve for x} \\ 3x-x=10 \\ 2x=10 \\ x=\frac{10}{2} \\ x=5 \end{gathered}

find AB

\begin{gathered} AB=3x \\ AB=3\cdot5 \\ AB=15 \end{gathered}

A

A right rectangular prism has base dimensions of 3 inches by 12 inches and a height of 5 inches. An oblique rectangular prism ha
KonstantinChe [14]
Yes they are. Given that a volume of a rectangular prism is V=l•w•h, we can plug them into an equation and compare them. I'll call the Right rectangular prism figure R and the oblique rectangular prism O


For Figure R, We know all the basic needs to find the volume. This means we can plug it in.

V=l•w•h
V=12•3•5
Now We can solve for V
V=12•15
V=180

The volume of the right rectangular prism is 180in^3


Now, For figure O.
V=9•4•5
V=9•20
V= 180.


With this in mind, We now can say that the volumes of both the rectangular prisms are the same.

Y and x have a proportional relationship, and y = 9 when x = 2. What is the value of y when x = 3?
Illusion [34]
Correct formula is y = kx, where k is the "constant of proportionality."

If y = 9 when x = 2, then 9 = k(2), or k = 9/2.

Then y = (9/2)x.

If x = 3, y = (9/2)(3) = 27/2  (answer)

Multiply 2 and then add 4 each time

3 x 2 = 6 + 4 = 10
10 x 2 = 20 + 4 = 24
24 x 2 = 48 + 4 = 52
