We can say L as length and W as the width
L= 3w + 8
The formula for perimeter is 2L + 2W = P. We can substitute L in as "3w+8" to make the equation...
2(3w+8)+2w=88 Now, we can simplify by distributing the 2 to each term
6w+16+2w=88
8w+16=88 Then subtract 16 from each side..
8w=72
w=9
So the width is 9, so we can substitue that into the previous equation, L = 3w+8.
L=3(9)+8
L=27+8
L=35, W=9
Round to the nearest significant number
275,000,000 = 2.75^8
2.75^8 is your answer
hope this helps

Consider the cup a cylinder. The formula for the volume of a cylinder is: V= PI x r^2 x h
Cup A: 3.14 x 7 x 1.5^2 = 49.46
This is large enough
Cup B: 3.14 x 5 x 1^2 = 15.7
This is too small
Cup C: 3.14 x 6 x 1.25^2 = 29.44
This is too small.
