Answer:
y = x² - 4x - 5
Step-by-step explanation:
y = x² - 4x - 5 = x² + x - 5x - 5 = x (x + 1) -5 (x + 1) = (x − 5) (x + 1)
x intercepts, value that cancels each: x = 5, x = -1
Let the first number = x
The second number would be 5x
The third number would be 100x
Add:
X + 5x + 100+x = 296
Simplify:
7x + 100 = 296
subtract 100 from both sides:
7x = 196
Divide both sides by 7
X = 196 / 7
X = 28
First number is 28
Second number is 28 x 5 = 140
Third number = 128
