length is nine inches less than twice width. L = 2W - 9
perimeter is 84 inches 2L +2W = 84
Substitute the expression for L (2W-9) for L in the second equation resulting in the follwing
2(2W-9) + 2W = 84
4W - 18 + 2W = 84
(4W+2W) = 84+18
6W = 102
W = 102/6 = 51/3
L = 2(51/3) - 9
= L= 17-9
L=6
Wow that's too much work!!! is this a table or printout?
All you have to do is divide 7,305 by 96 to see how many apples can she fill in a box and how many will be left over
Using the given formula, replace sa with the given surface areas and solve for s:
Surface area = 1200
s = √1200/6
s = √200
s = 14.142
Surface area = 768
s = √768/6
s = √128
s = 11.313
Difference:
14.142 - 11.313 = 2.829 inches
Round answer as needed.
Answer:
w⁴ + 3w³ + 11w² + 6w + 18
Step-by-step explanation:
Rectanle area = height * width
area = (w²+3w+9)(w² + 2)
= w²*w² + w²*2 + 3w*w² + 3w*2 + 9*w² + 9*2
= w⁴ + 2w² + 3w³ + 6w + 9w² + 18
= w⁴+ 3w³ + (9w²+2w²) + 6w + 18
= w⁴ + 3w³ + 11w² + 6w + 18
