Answer:

Step-by-step explanation:

Two triangles.

one triangle = 1/2 * small leg * middle sized leg

one triangle = 1/2 * 3 * 4

One triangle = 6

Two triangles = 6 * 2 =                                            12

Front

Area = L * W

L = 8

W = 5

Area = 8*5                                                              40

Left Side

L = 8

W = 3

Area = 8*3

Area = 24

Area=                                                                     24

Right Side

L = 8

W = 4

Area =                                                         <u>          32</u>

Total Area = 32 + 24 + 40 + 12                          108

There is another way to do this.

Since the height is the same for all three faces, you can do it like this

Area = 8*(3 + 4 + 5) = 8(j12) = 96

Area of the two tiangles     = 12

Total area =                          108

Answer:

3 x 4 = 12, 12 divided by 2 ) x 1/2) = 6, 6 x 2 = 12(area of two triangles)

8 x 4 = 32

8 x 3 = 24

8 x 5 = 40

Let's add all the given areas:

12 + 32 + 24 + 40 = 108 m^2 is your answer.

Rate of change is another way to say slope.

Slope is (the change in y) / (the change in x).
The formula for slope is:
m = (y2 - y1)/(x2 - x1), with (x1, y1) being one point and (x2, y2) being the second. What you need to do is order the slopes from smallest to largest because slope means the same thing as rate of change.

#17. First, you need to find the slope of function A. To do this, I’m choosing two different points I see on the graph: (1,1) and (2,1). I now plug these into the slope formula:
m = (1-1)/(2-1) = 0/1 = 0.
The slope for function A = 0

To find the slope for function B, you can choose any two points. I’m going to use (3,0) and (6,1)

m = (1-0)/(6-3) = 1/3
The slope for function B is 1/3

For function C, you are already given the slope. That equation is in something called slope-intercept form (y=mx+b), where the x is being multiplied by the slope.
The slope on function C = 1/4

So,, A has the smallest slope, C has the second smallest slope, and B has the largest slope.

#18. The two points in using to find the slope for function A are (0,-3) and (1,0).
m = (0+3)/(1-0) = 3/1 =3
The slope for function A is 3

The two points I’m using for function B are (-2, 10) and (0, 20)
m = (20-10)/(0+2) = 10/2 = 5
The slope for function B is 5

The slope for function C is 1. When the slope is 1, it is not written because any number (other than 0) times 1 equals 1.

Function C has the smallest slope, function B has the second smallest slope, and function C had the largest slope.

It would probably be better for you to try 19 and 20 on your own, and let me or anyone else on Brainly know if you have any questions or something doesn’t make sense.
I hope this has helped!
