The entire large rectangle above is 38 units long and 2 units wide.
Its area is length times width, so the area is 2 * 38.
38 is also the same as 30 + 8, so the area can also be written as 2(30 + 8).

The left rectangle is 30 units long and 2 units wide. Its area is 2 * 30.
The right rectangle is 2 units long and 8 units wide. Its area is 2 * 8.

If you add the areas of the small rectangles, you get
2 * 30 + 2 * 8

If you add the two small areas, you get the area of the laerge rectangle, so

2(30 + 8) = 2 * 30 + 2 * 8

which is an example of the distributive property.

The table represents a linear function.What is the slope of the function?
Viktor [21]

Answer:

the slope is 4/3

Step-by-step explanation:

use the formula:

m=\frac{y1-y2}{x1-x2}

where x1 and y1 can be any point and x2 and y2 can be any point.

I used the last relation as my x1,y1 and second last relation as my x2,y2 because it is easier to subtract them.

\frac{10-2}{7-1} which is 8/6 or 4/3

Finger [1]

We have 2 angles that are supplementary, so their sum equals 180⁰.

(4x - 10) + (7x - 8) =180

11x - 18 = 180

11x = 198

x = 18
