What are factors of -20 that when added together equals 8?

10 and -2

Step-by-step explanation:

We can say that

p*q should equal to -20, and

p + q should equal to 8

If p is 10 and q is -2, then

10*-2 = -20

10 + (-2) = 8

Therefore answer = 10 and -2

Hope this helps!

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
