Answer:
Step-by-step explanation:
(x² + 6x + 9)(x)= x²*x + 6x*x + 9*x = x³ + 6x² + 9x
105 m = 2.5 h
x miles = 1 hour
You cross multiply since it's a proportion:
2.5 * x
105 * 1
=
2.5x = 105
Then you divide everything by 2.5
The answer is 42
The solution to 5x=35 is..
X=7
5x\5=35/5
Answer:
Step-by-step explanation:
3x²-5x+2=0
3x²-3x-2x+2=0
3x(x-1)-2(x-1)=0
(x-1)(3x-2)=0
either x-1=0 which gives x=1
or 3x-2=0
x=2/3
