You know if it's not reducible when there isn't any way to factor it using the grouping method. However, you should try to use the quadratic formula to find the roots after attempting to factor. If it still doesn't have any roots, that means the quadratic's vertex is either above or below the x-axis and is facing the other way. (meaning that it never touches the X-Axis)<span />
Answer:
5 5/8 miles per hour
Step-by-step explanation:
Martin can run 3 ¾ miles in 2/3 of an hour. Write a unit rate to describe the situation and explain the context.
We are asked to write the unit rate , this means we are to find out how many miles he can run per hour
Hence,
2/3 hour = 3 3/4 miles
1 hour = x
Cross Multiply
2/3 hour × x = 3 3/4 miles × 1 hour
x = 3 3/4 miles × 1 hour/ 2/3 hour
x = 3 3/4 ÷ 2/3
x = 15/4 ÷ 2/3
x = 15/4 × 3/2
x = 45/8
x = 5 5/8 miles per hour
Lcm because a multiple is always greater then a factor.
