3x^2 - 5x - 2
3x^2 - 6x + x - 2
3x (x - 2) + 1 (x - 2)
(3x + 1) (x - 2)
Answer:
The bottom is 11
The median is 12
Step-by-step explanation:
The median is the average of the top and bottom
(13+ 2x-3) /2 = 4x-16
Combine like terms
(10+2x)/2 = 4x-16
Divide by 2
5+x = 4x-16
Subtract x from each side
5+x-x = 4x-16-x
5 = 3x-16
Add 16 to each side
5+16 = 3x-16+16
21 = 3x
Divide by 3
21/3 = 3x/3
7 =x
The bottom is 2x-3 = 2*7-3 = 14-3 = 11
The median is 4x-16 = 4*7-16 = 28 -16 = 12
8.75*40=350
time and a half=13.125
7.5 hours * 13.25= 98.4375
total 448.4375
The answer is 4ft. you just have to convert the size of the wall and the size of the window to the same thing. Like I converted 9.75 to 39/4. Then you just subtract and what you have left is the answer. Hope I explained that well.
