P²+7p+10=(p+2)(p+5) and p²+5p+6=(p+2)(p+3) so the LCD is (p+2)(p+3)(p+5).
The first fraction becomes (p+3)²/((p+2)(p+3)(p+5)) and the second fraction becomes p(p+5)/(5(p+2)(p+3)(p+5)).
Answer:
6 hours
Step-by-step explanation:
70 ÷ 4 = 17.5 ----- divide to find out how many miles she travels per hour.
Samantha is driving at 17.5 mph
105 ÷ 17.5 = 6 ----- divide to find out how long it will take to travel that distance.
distance ÷ time = speed
distance ÷ speed = time
We would use the sine function because we have an angle the hypotenuse, and the unknown opposite side.
sin(x)=opposite/hypotenuse
sin(60)=x/30
√3/2=x/30 (cross multiply)
30*√3/2=x (divide numerators and denominators by 2)
x=15√3 ft.
So the correct answer is A
Hope this helps
