First you find the base of the big triangle which is also the same bass of the small triangle, so you use the pythagoras theorem on the small triangle and you get: 8 (the first picture)

After that you have 2 sides of the big triangle so you do the pythagoras theorem again and you get: 17 (second picture)

Two negative integers are 8 units apart on the number line and have a product of 308.
Svetach [21]
Calll x the smaller negative number.

The larger number will be x + 8

The product will be x(x+8) = 308

An the equation:

x^2 + 8x = 308
x^2 + 8x - 308 =0

If you solve that equation you will get x = -22 and x = 14.

The result that you are looking is the negative, x = -22.

The larger number is -22 + 8 = -14.

(-22)*(-14) = 308

Answer: x^2 + 8x - 308 =0
