Answer:
B
Step-by-step explanation:
if the third number is 7 and the difference is -5, and you're trying to find the fourth number, you would simply subtract 5 from 7 to get 2 as your fourth number.
Answer: -1
Step-by-step explanation: To evaluate this problem, the first thing we want to do is plug in the appropriate value for <em>x</em>.
When we do that, we get
A good rule of thumb for problems that involve division bars is to simplify what's above the division bar as much as you can and what's below the division bar as much as you can before you do your dividing.
So up top if we follow our order of operations, the first thing we want to do is square the -2 before we subtract. So -2² is +4.
So in our numerator we have 4 - 8.
Down below, we have -2 + 6 which is +4.
4 - 8 is -4 and -2 + 6 is +4.

Step-by-step explanation:
Answer: 26/21 or 1 and 5/21
Step-by-step explanation:
Dividing by a fraction is the same as multiplying by the reciprocal, so you can rewrite this problem as (4/6) x (13/7)
Next, multiply the numerators (4 and 13) and the denominators (6 and 7)
You will get 52/42, which can be simplified to 26/21 (you can also write this as 1 and 5/21)
Hope this helps
Answer:
(8 + x)(8 - x)
Step-by-step explanation:
Use the DIFFERENCE OF TWO SQUARES METHOD.
Find the like terms. There are NO like terms. We have to use THE DIFFERENCE OF TWO SQUARES FORMULA.
64 - x²
8 - x + 8 + x
(8 + x)(8 - x)
