Step-by-step explanation:
2 miles: 1/2 hour
? mile: 1 hour
(2÷1/2)mi/h or B is your final answer. Hope it help!
7(3a + 12) = 168 ← ( divide both sides by 7 )
3a + 12 = 24 ← ( subtract 12 from both sides )
3a = 12 ← ( divide both sides by 3 )
a = 4
OR
distribute the parenthesis by 7
21a + 84 = 168 ← ( subtract 84 from both sides )
21a = 84 ← ( divide both sides by 21 )
a = 4
Answer:
6
Step-by-step explanation:
Pull terms out from of the radical,assuming positive real numbers .
This is a notable trinomial.
You have to find two number which summed give 5 and multiplied give 6
In this case 2 and 3
2+3 = 5 and 2*3 = 6
So (y+2)(y+3)
