Answer:

The answer is : 23.25 in ²

Step-by-step explanation:

There are 3 triangles with the same lengths: height = 5in and base = 5 in

There is one triangle: height = 4.3 in base = 5 in

Formula

Area = height x base / 2

For the triangles

Area = 5 in x 5 in /2 = 25 /2 = 12.5 in²

For the triangle

Area = 4.3 x 5 /2 = 21.5 /2 = 10.75 in²

Total surface area = 12.5 + 10.75 = 23.25 in²

The length would be 6 centimeters. You would get this answer because 6 divided by 3 is 2. So you would divide 18 by 3 and get 6. So the length of the second rectangle is 6 centimeters. Hope this helps!
Have a great day!

Can someone help me find the slope?
kipiarov [429]

Answer:

Undefined

Step-by-step explanation:

First, take 2 points from the table given, then you use the equation y2-y1/x2-x1 to find your slope. So, if I take the coordinates (7,1) and (7,2) and plug them into my equation, I would get 2-1/7-7. If you solve this equation, you will end up wil 1/0. Now, if you have something like this as your answer, you can not find your slope. There can not be a slope because the zero is at the bottom, making this "Undefined".
