ANSWER
y = 100 + 0.25(160) - equation
y = 140 - if you needed the answer
Answer: 3060 ft^2
Step-by-step explanation:
We will calculate the surface area of the rectangular prism and the triangular prism separately and then subtract off the face that isn't on the surface.
For the rectangular prism:
SA= Ph + 2B
P = 36+36+10+10
P = 92
B = 36*10 = 360
SA = 92*20+2*360
SA = 1840+720
SA = 2560
We subtract off the face on the right of the rectangular prism because it isn't on the surface so we get 2560-200 = 2360
Now for the triangular prism:
SA= Ph + 2B
P = 15+20+25
P = 60
B = 15*20/2
B = 150
SA = 60*10+2*150
SA = 600+300
SA = 900
Again we subtract off the face on the left bescause it's not on the surface so we get 900-200 = 700
Therefore, the total surface area = 2360+700 = 3060 ft^2
First add the to variables together
2.3x-5.4=10
Then subtract 5.4 from 10
2.3x=4.6
then divide by 2.3 on both sides of the equal sign
finally your answer is: 2
Step 3 is the frist incorrect step it should be: 2x-3=3 or 2x-3=-3
