N^2=-35-12n how answer this question

n² = -35 - 12n  

Add 12n and 35 to both sides

n² + 12n + 35 = 0

Find the factors of 35 that add or subtract to positive 12:

Factors of 35: 1, 5, 7, 35

5 and 7 add up to 12

n² + 12n + 35 = 0

Instead of 12n, you can replace it with 7n + 5n because they add up to 12n

n² + 7n + 5n + 35

Factor the equation separately

n(n + 7) + 5(n + 7)

Now factor out the (n + 7)

(n + 7)(n + 5)

d

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
