Answer:
A) 14/9
Step-by-step explanation:
14 and 9 have no GCFs (Greatest Common Factors), so the ratio is simply 14/9.
Convert 3 hours and 30 minutes all into minutes so that would be 210 minutes. You then have 169 miles / 210 minutes. Get the denominator to 1 minutes by dividing by 210 to the top and bottom and you'll get .080476 miles / 1 minute which is the answer.
perimeter of a square is 4 times side length (4s)
to find the length of a side divide the perimeter by 4
53.2 / 4 = 13.3
so each side is 13.3 inches
Factor the following:
5 x^2 + 20 x + 15
Factor 5 out of 5 x^2 + 20 x + 15:
5 (x^2 + 4 x + 3)
The factors of 3 that sum to 4 are 3 and 1. So, x^2 + 4 x + 3 = (x + 3) (x + 1):
Answer: 5 (x + 3) (x + 1)
