BRAINLIEST correct answer
Find the surface area of this triangular prism.

possible answers

a144 square centimeters

b138 square centimeters

c156 square centimeters

d32 square centimeters

a144 square centimeters

Step-by-step explanation:

RIght triangle: 1/2(4)(3)=6

6*2=12

Area of Rectangle: 11(5)=55

Area of back rectangle: 3(11)=33

Area of bottom rectangle: 11(4)=44

44+33+55+12=144

Therefore, 144 cm^2

explanation

the graph has a slope of 1/3 because each time you move up 1, you go to the right 3. so, slope = rise/run = 1/3. we can cross choice a off the list since we want a slope of 3, rather than 1/3.

the first table shown has a slope of -3. this is because the rise is -6 and the run is 2, so slope = rise/run = -6/2 = -3. note how x increases by 2 each time (run) and y drops by 6 each time (rise). choice b can be eliminated.

the second table has a slope of 3. each time x goes up by 1, the y values increase by 3. slope = rise/run = 3/1 = 3. alternatively you can use the slope formula to prove that the slope is 3 here. use any two rows of values to generate the two points. choice c is one of the answers

the third table also has a slope of 3. let's use the slope formula to prove as such. i'm going to use the first two rows of the table. so i'll use the two points (2,1) and (5,10)

m = slope

m = (y2-y1)/(x2-x1)

m = (10-1)/(5-2)

m = 9/3

m = 3 so we get a slope of 3

choice d is the other answer
