What are factors of -40?
(-20)(2)
(-10)(4) (sum of these factors is 6, which is not what we wanted)
(-5)(8) = -40 and the sum of the factors (-5) and (8) is 3.
{-5, 8} is the list of factors of -40 that add up to 3.
Answer:
he has 1/6 of a piza left
Step-by-step explanation:
becuase if you take the left over pizza, 3/4 it is bacially only a quarter of the piza gone, if image a pizza half of the circle is there, and half of the half circle is also there, and that is 3 sections, 6 d 3 get along, so ecaily each of the 3 section are wroth 2 slices and he ate 5, so 1 is left.
The right answer is not among those offered. The domain is
.. {-9, -6, 4, 7}
___
The 4th selection {4, 7} is the best of those offered, but it is not correct.
Answer:
The last option.
Step-by-step explanation:
Well, in this case, the a-value is 1, b-value is -9, and c-value is 5.
You would have -(-9) plus or minus the square root of ((-9)^2) - 4 * 1 * 5, divided by 2 * 1.
That would be [9 plus or minus sqrt(81 - 20)] / 2
= [9 plus or minus sqrt(61)] / 2
That is the last option.
Hope this helps!
