Answer:
- c = 2
- segments 10, 8, 6 (top down)
Step-by-step explanation:
The sum of top and bottom bases is twice the midsegment.
(c² +6) +(c² +2) = 2(4c)
2c² -8c +8 = 0 . . . . . . . . . subtract 8c
2(c -2)² = 0 . . . . . . . . factor
c = 2 . . . . . . the value that makes the binomial be zero
The value of c is 2; the segment lengths (top-down) are 10, 8, 6.
12*14*3= 504 square feet
504/42= 12
C. 12 rolls
There is an understood decimal behind the 0. move the decimal two places to the left. making it .50. <span />
Answer:
x^2 -3x +15
Step-by-step explanation:
7x^2 +6x -9x - 6x^2 +15
Combine like terms
7x^2 - 6x^2 +6x -9x +15
x^2 -3x +15
The manager’s likely error was forgetting to add the $2 back to the $18. Because $2 is roughly 11% of $18 for a markup you need to add the $2 back into the $18 for a total of $20.
