Let's go through the steps of factoring that Venita should take.
1.) Find the greatest common factor (GCF). We only have two terms, so that makes it pretty easy.
32 = 1, 2, 4, 8, 16, 32
8 = 1, 2, 4, 8
The greatest common factor of 32 and 8 is 8. We can also factor out a b since that term appears in each part of the original expression. The GCF and variable should go on the outside of the parentheses.
8b( )
2.) Now let's figure out what should go in the middle of the parentheses. To do this, use the original expression and divide each term. This is written in the parentheses.
32ab ÷ 8b = 4a
8b ÷ 8b = 1
This would then result in the factored expression 8b(4a - 1). You can always check this by using the distributive property. Distribute 8b out to both expressions:
8b x 4a = 32ab
8b x 1 = 8b
32ab - 8b is the expression she started with, so your factored expression works!
Now that we went through the steps to solve the factored expression, let's check her answer. The only difference between Venita's and ours is that she has 0 as the second term while we have a 1. It seems that she had subtracted the GCF from the second term instead of dividing.
Answer:
16
Step-by-step explanation:
step 1: 3 x 7 = 21
so you're left with this 21-25/5
step 2: 25/5=5
left with 21-5
step 3: 21-5=16
16 should be the right answer, sorry if i'm wrong
Answer:
If the reference value was one then shouldn't it be 6.1 times more?

The differences between adjacent terms of an arithmetic sequence are the same.
No sequence in which signs alternate can be an arithmetic sequence. This eliminates the 1st and 4th choices.
The denominators of the 2nd sequence are an arithmetic sequence, meaning that sequence is a "harmonic" sequence, not an arithmetic one. The differences between adjacent terms get smaller and smaller. They are not a constant.
Differences between terms of the 3rd sequence are all 3/2. This is your arithmetic sequence.
Distance = velocity x time
distance = 9.6 x 10^15 meters
velocity = 3x10^8 meters/second
time = distance / velocity = m / (m/s) = s
