4x + 10 = 2x + 20
4x - 2x = 20 - 10
2x = 10
x = 5
3/5 = 60/100 = 0.6
65
x 60
= 00
3900
3900 / 100 = 39.
While going through construction, the car travels at 39mph.
Answer:
(x-3)(x-5)
Step-by-step explanation:
X^2-8x+15
Break the expression into groups
(x^2-3x)+(-5x+15)
Factor out x from x^2-3x
Factor out -5 from -5x+15: -5(x-3)
=x(x-3)-5(x-3)
Factor out common term x-3
=(x-3)(x-5)
