Add all the numbers up and divide by 5 to get your answer. I believe in you.
The two factors of a quadratic equation can be multiplied to form the original equation. Let the missing term be a:
y² + 15y + 56 = (y + 7)(y + a)
y² + 15y + 56 = y² + (7 + a)y + 7a
We can now compare the coefficient of the like terms, either the one with y or the one without y, and find the value of a.
15 = 7 + a; a = 8
OR
56 = 7a; a = 8
Second factor is (y + 8)
5.5 always goes between 5 and 6
remember (x,y) one of the dots goes on the exactly on the axis, you have to drag it down to -9 from the y-axis
Answer:
it is scalene type of triangle because no sides are equal
