Answer:

x=1

Step-by-step explanation:

Given is a picture of a parallelogram ABCD

As per properties of parallelograms opposite sides are parallel and equal.

Two opposite sides are given as 12.

But another pair is given in terms of x as 16+2x and 10+8x

Since opposite sides would be parallel we have

16+2x =10+8x

Simplify to get

6x =6

or x=1

Verify:

The top side = 16+2x =18

The bottom side 10+8x = 10+8 =18

Thus both are equal, thus verified

This shape is a parallelogram and the opposite sides of a parallelogram

are of equal length.

10 + 8x = 16 + 2x ⇔ 8x - 2x = 16 - 10 ⇔ 6x = 6 ⇔ x = 6:6 ⇔ x = 1

To estimate the volume of Thai triangular prism you will use the formula for finding the volume.

V=Bh, where B is the area of the base and h is the height of the prism.

V = (1/2 x 12.6 x 1.6) x 10.75
V = 108.36 cubic mm

You answer is approximately 108 cubic millimeters.

4x+8y=17<br> Solve for y

olasank [31]

Answer:

4x + 8y = 17

Solve for y.

You want to get y on one side of the equal sign by itself so... you subtract 4x from both sides to get:

8y = -4x + 17

Then you divide both sides by 8 to get:

y= -4x/8 +17/8
