Answer:
See below
Step-by-step explanation:
Using formula
- x^2 - y^2 = (x + y)(x - y)
Applying to given expression
- 36 - 9 =
- 6^2 - 3^2=
- (6 + 3)(6 - 3)=
- 9*3=
- 27
(6x^2+5x+1)/(3x^2+4x+1)
= (3x+1)(2x+1)/(3x+1)(x+1)
= (2x+1)/(x+1)
Michelle can fold 4/54 baskets per minute = 8/108 baskets per minute.
Ruby can fold 4/108 baskets per minute.
Each minute Michelle and Ruby work together, they can fold
8/108 +4/108 = 12/108 = 1/9
of a basket of clothes. For 8 baskets of clothes, it will take them
(8 baskets)/(1/9 baskets/minute) = 72 minutes
To reach 60 miles in 45 minutes you’ll have to drive 80mph
