??????????????????????
Step-by-step explanation:
mmm+#-#+273(-2(2
Answer: 9
Step-by-step explanation:
1- bigger triangles points are (x,12)
Smaller triangles points are (6,8)
Do a proportion
6/8 = X/12
= 9
For this case suppose that we have a quadratic equation of the form:
![ax ^ 2 + bx + c ](https://tex.z-dn.net/?f=ax%20%5E%202%20%2B%20bx%20%2B%20c%0A)
The solution to the quadratic recuacion is given by:
![x = \frac{-b +/- \sqrt{b^2 - 4ac}}{2a}](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B-b%20%2B%2F-%20%20%5Csqrt%7Bb%5E2%20-%204ac%7D%7D%7B2a%7D%20)
Where,
The discriminant is:
![b ^ 2 - 4ac ](https://tex.z-dn.net/?f=b%20%5E%202%20-%204ac%0A)
When the discriminant is greater than zero, then the root is positive, and therefore, we have two positive real solutions.
Answer:
B. it has two real solutions
