I don't have an idea about the 1st one but second one goes by subtracting 1/3
subtract 1/3 from 8 1/3 it's 8, subtract 1/4 from 8 it's 7 2/3. figuring out the patterns are simple most of the time bu you can get stuck sometimes, if you wanna get better, practice...

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
Answer:

Standard form: Ax + By = C
slope intercept form: y = mx + b
point slope form: y - y1 = m(x - x1)
lets use this equation as an example:
8x + 4y = 16 first subtract 8x
4y = -8x +16 then divide every number by 4
y = -2x + 4 this equation is now in slope intercept form
