Answer:
5(4 + 3c) - 12 = 15c + 8
Step-by-step explanation:
1st step, expand it to make it a little easier to solve, 20 + 15c - 12
2nd step, subtract, 20 - 12 = 8
3rd step simplify, 15c + 8
Answer:
1. 12 ft
2. 42.86 ft
Step-by-step explanation:
1. 5/24 = 2.5/<em>x</em>
<em> </em>5x<em> </em>=<em> </em>60
<em> x = </em>12 ft
2. 5/<em>x</em> = 7/60
7<em>x</em> = 300
x = 300/7 = 42.857 ft
Okay so Take a calculator and go down each row. Start with 2. Then shade those. Then move to 3 and go through each box that isn't shaded and so on and so fourth
For prisms: V = Bh where B is the area of the Base of the prism and h is the height of the prism.
B = 12(20)
B = 240
Now let's substitute into:
V = Bh
4800 = 240h divide both sides by 240
20 = h
So the height of the prism is 20 cm
