3x^3-24x^2=> this is the expression, find what they have in common: 3 and x^2
3x^2(x-8)=> so we took out 3x^2
I hope this helps you:)!
|x| this means absolute value making what ever number in the inside positive UNLESS you have a negative out front. Ex |8|=8. -|8|=-8. |-8|=8
Let x be the number of cars. We will find out how many cars you have to wash to make as much money as your friend:
10x - 25= 13x - 55 Add 25 on both sides and subtract 13x, also both sides:
3x = -30 Now divide both sides by -3:
x= 10 cars you have to wash.
Answer:
Step-by-step explanation:
diameter = 8 cm
radius = 8/2 = 4 cm
Area of circle = πr²
= 3.14*4*4 = 50.24 cm²
Answer:
I think it is E and C
Step-by-step explanation:
E) y - 6 = -7/4(x+5)
(-5,6)
6-6=-7/4(0)
0=0
(-1,-1)
-1-6=-7/4(-1+5)
-7=-7/4(4)
-7=-7
