Ax^2+bx+c=0
a=2
b=-1
c=-3
b+-sqrt( b^2 - 4ac)
          2a

so...
-1 +- sqrt(1 + 24)
           4
-1 +- 5
    4
x= -1 + 5 = 1
         4
or
x= -1 - 5 = -3/2

Ummm sooo I’m really confused and it’s due tomorrow please help me
MaRussiya [10]

Answer:

75

Step-by-step explanation:

If the triangles are similar, it means the ratio between the two give sides is the same. As seen from the smaller triangle the ratio of the two top sides would be 16:50 or 8:25.

Since the first side of the bigger triangle (24) is three times 8 (it's ratio side), then the other side must be 3x25 = 75, which maintains the ratio 8:25 between the two sides (24:75).

Hope this helped!
