15. m = 15 because 15/3 = 5 and 5-1 = 4
|-5|, -3, -1, |2|, 6 (I’m not 100% sure, but I think this should be correct)
Answer: The length is 6 feet and the width is 10 feet.
Step-by-step explanation: The question has specified the area as 60 (square feet) and the length and width are yet unknown. However we know that the length is 4 feet less than the width. What this means is that, if the width is W, then the length is W - 4.
We can now write an equation for the area of the rectangle as follows;
Area = L x W
60 = (W - 4) x W
60 = W^2 - 4W
If we rearrange all terms on one side of the equation, we now have
W^2 - 4W - 60 = 0
This is a quadratic equation and by factorizing, we now have
(W + 6) (W - 10) = 0
Hence,
Either W + 6 = 0 and then W = -6
Or W - 10 = 0 and then W = 10
We know that the side of the rectangle cannot be a negative value, so we go with W = 10.
Having calculated W as 10, the length now becomes
L = W - 4
L = 10 - 4
L = 6
Therefore, length = 6 feet and width = 10 feet
Answer:
-22
Step-by-step explanation:
Each gap segment is the value of 3.
T= Total cost
m= # of members
Total equals $60 fee plus ($15 times # of members) plus $95 fee plus ($12 times # of members)
T= $60 + $15m + $95 + $12m
combine like terms
EXPRESSION:
T= $27m + $155
Hope this helps! :)
