We can make this expression to find out what 49% of 3120 and 2130:
49% * 3120
49/100 * 3120
152880/100
1528.8
49% of 2130
49/100 * 2130
104370/100
1043.7
Answer:
You find the surface area with:
10*2+10*2+4*2+4*2+2*2+2*2+4*7+4*7+4*4+4*4 or in short 152 in^2.
Answer:
3(4.5) Because they equal the same thing
Step-by-step explanation:

3(4.5)=13.5
120 / 18 = 20/3
x^3 / xy = x^2 / y
20x^2 / 3y
