The answer is 28.
<span>(x – 13)(x + 8) = 196
</span>x * x + x * 8 - 13 * x - 13 * 8 = 196
x² + 8x - 13x - 104 = 196
x² - 5x - 104 - 196 = 0
x² - 5x - 300 = 0
The general quadratic formula is ax² + bx + c = 0
In our equation: a = 1, b = -5, c = -300
So, missing length is either:
x1 + 8 = 20 + 8 = 28
or
x2 + 8 = -15 + 8 = -7
Since, length of a triangle cannot be negative, the missing side length is 28
Answer:
11.047---68.168---89.51
Step-by-step explanation:
just switch 11 and 89
6y-4=4y+2
2y=6, so y=3.
Plugging it in, you get that AC equals 4*3+2=14.
This is an isosceles triangle.
