Answer:
4 is the best answer for it
<u>Answer: </u>14x - 11y
<u>Step by Step Explanation: </u>
- Ignoring that first half, your first step is to distribute the subtraction sign
-(-5+9y-8x) —-> 5-9y+8x
- Next, combine like terms
- Your x terms, y terms, and regular numbers
6x-2y-5+5-9y+8x
6x+8x-2y-9y-5+5 (reorganizing terms so that they’re together can be helpful for some people, but it’s not necessary)
6x+8x = 14x, -2y-9y = -11y, -5+5 = 0/Cancel each other out
This leaves you with 14x-11y
Around 150 rotations
I rounded the radius to feet which is 1 foot. Then you have to get the diameter which is 1x2=2. The diameter is 2 feet. Now for the circumference, we multiply 2 by 3.14(which is pi). The answer to that is 6.28, and since we are rounding it, we get 6 feet. However, we are traveling 900 feet. Divide 900 by 6 and get 150.
P=84=2l+2w
l=2*w+6
84=2(2w+6)+2w
84=4w+12+2w
72=6w
w=12
l=2*12+6
l=30
length is 30 meters and the width is 12 meters
