The first mistake was in the 6x + 14 = -4 Line as -12x + 6x is -6x and not 6x.
3 (m + 5 + 9m)
Two expressions that are e<span>quivalent to the given expression are:
3m + 15 + 27m
or
30m + 15
you get both expressions by multiplying the original expression
the second expression is obtained by adding the like terms</span>
Answer:
2488 miles
Step-by-step explanation:
The relevant relationship is ...
distance = speed × time
For each leg ...
distance 1 = (264 mi/h) × (2 h) = 528 mi
distance 2 = (490 mi/h) × (4 h) = 1960 mi
Then the total distance traveled in the 6 hours is ...
distance traveled = distance 1 + distance 2 = 528 mi + 1960 mi
distance traveled = 2488 mi
Answer:
1.1726.
Step-by-step explanation:
Use the identity sec^2 O = 1 + tan^2 O
sec^2 O = 1 + 3/8 = 1.375
sec O = √(1.375)
= 1.1726.
