-2(-53)×36-24-36 》3816-60=3756
No, surface area and total surface area are the same.
Answer:
perimeter of rectangle= 2(l+w)
34=2(l+6.5)
34= 2l+13
2l=34-13
<u>2l</u>=<u>21</u>
2. 2
l= 10.5 units
The area of the red piece of paper is A= 4(2*4)= 4*8= 32 in^2.
The area of the blue piece of paper is A= 3*7=21 in^2. You subtract 21 from 32 and the difference is 11. So 11in^2 is visible.

<em>Identify</em>
3x + 2 = 17
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Subtraction Property of Equality] Subtract 2 on both sides: 3x = 15
- [Division Property of Equality] Divide 3 on both sides: x = 5
