Answer:
1. D
2. H
3. D
Step-by-step explanation:
1. It is y=mx+b m is slope and b is Y intercept
2. You make it to be in y=mx+b you find the slope and you find where Y is
3. An easy but tedius way is to go to all and plug in the numbers (x,y) or you can first find the slope with the slope formula
Since we have a rectangle triangle, then we can find the other side of the triangle using the Pythagorean theorem.
We have then:

Then the surface area is given by the sum of the areas.
Triangle of the base and the top:

Rectangle 1:

Rectangle 2:

Rectangle 3:

Finally, the surface area is:

Substituting values:
Answer:
The surface area of a right triangle prism is:
B. 132
63 = 0.63×10² = 126/2 = 3×21 = √3969 = 77₈
The last is as a base-8 number.
Check all the ones listed below:
1. The base is 3
(you are multiplying 3 four times or 3 to the power of 4 )
2. The exponent is 4
( 3 is the number you are multiplying and the exponent or 4 tells you how many times you multiply the base which is 3)
3. The exponent tells you to multiply the 3 together 4 times
( 3x3x3x3 is multiplying the number 3, 4 times)
