Answer:
A. 6(8+13)
Step-by-step explanation:
As far as I know, when I distribute each one, they all come out with the same answer except for D in which it doesn't equal to 48 + 78. I say A is the answer because of its GCF in which it is the most you can distribute for.
Answer:
40
Step-by-step explanation:
The angles are equal to eachother so 4x-26 = 3x+14
Step-by-step explanation:
x = downstream speed in mph
4 hours × (x-10) + 3 hours × x = 58 miles
4x - 40 + 3x = 58
7x = 98
x = 14 mph downstream speed
and as extra :
therefore his upstream speed was 14 - 10 = 4 mph
