The question gives you 4 different numbers that could be x, so you have to replace each x in each problem and solve. If the two answers are equivalent, that is your answer. For the first one, 6 times 2 is 12, minus 2 is 10. 5 times 2 is 10, plus 3 is 13. 10 is not equal to 13, so that is not the answer. For 5, 6 times 5 is 30, minus 2 is 28. 5 times 5 is 25, plus 3 is 28, so therefore the answer is x=5
Answer:
x^2+7x+12
Step-by-step explanation:
(x+3) (x+4)
FOIL
first: x*x = x^2
outer: 4x
inner: 3x
last: 3*4 =12
Add them together
x^2 +4x+3x+12
x^2+7x+12
Answer:
Interphase: 55.56%
Prophase: 27.78%
Metaphase: 8.33%
Anaphase: 5.56%
Telophase: 2.78%
Step-by-step explanation:
All you need to do is follow the instructions. To get the percentage, all you need to do is divide the part by the whole then multiply it by 100%.

Now let's take your problem:
Number of cells in interphase:
20 this is the part and the whole would be the total cells, which is 36. Now we insert that into our equation:

So now we apply the same to the rest:
Prophase:

Metaphase:

Anaphase:

Telophase:

Answer:
They will win 48 games in a 120 game season.
Step-by-step explanation:
The team won 20 games out of 50; that is a 20:50 ratio, that is equal to x:120. x is the amount of games won in the 120 game season.
Set up the ratios like this:
= 
cross multiply the numerators and denominators to get this:
20*120 = 50x
solve for x:
2,400 = 50x
x = 48
