Answer: 150m
Step-by-step explanation: you first remove 5 from 20 to get what you should multiply for your triangle then you get 15 and multiply it by 12 to get 180 then you divide by 2 since it’s a triangle, to get 90 then you find the area of the rectangle by multipling 5 by 12 to get 60 then 60+90=150
Answer:
The second one
Step-by-step explanation:
3 ft = 12 * 3 = 36 inches wide
36 / (3/4) =
36 * 4/3 =
144/3 =
48 books can fit
5+3x=37
Step 1
subtract 5 from both sides
3x=32
Step 2
divide by three
x=10.6(repeating)
Times the two radicals together
So it's:
8*sqrt 15*5 (find common numbers between 5 and 15 which is 5)
8*sqrt(5^2*3)
8*5 sqrt3
40 sqrt 3
