Answer:
b
Step-by-step explanation:
1. Distribute the -2x with the (x+3)
2.Multiply (x+1) and (x-2) which is (x2- x -2)
So far it should look like (-2x^2 -6x) - (x^2-x-2)
3. Distribute out the negative
Should look like this -2x^2 -6x - x^2+x+2
4. Lastly combine like terms
Your result should be:
-3x^2 - 5x + 2

Circumference of the wheel = pi*d = 26pi ins = 13pi / 6 feet
there are 8280 feet in 1 mile
The number of revolutions in travelling 1 mile = 5280 * 6
----------- = 776 revs

Answer: 10
25% of 80 is 20 ( 80 x .25 = 20)
20 / 2 = 10
Answer:
4/7 =x
Step-by-step explanation:
6 - 2/3(x+5)=4x
Multiply each side by 3 to clear the fraction
3(6 - 2/3(x+5))=4x*3
Distribute
18 -2(x+5) =12x
Distribute the 2
18 -2x-10 = 12x
Combine like terms
8 -2x = 12x
Add 2x to each side
8-2x+2x =12x+2x
8 = 14x
Divide by 14 on each side
8/14 =14x/14
4/7 =x
