Answer:
x = 40 1/2
Step-by-step explanation:
The hash marks tell you the triangles are similar and the smaller one is 1/2 the size of the larger one. Then x is half the length of the corresponding segment marked 81.
x = 81/2
x = 40 1/2
___
You may have to write it as 81/2 or as 40.5. Sometimes the answer needs to be in a particular form.
Answer:
-4/15
Step-by-step explanation:
-3/5+1/3 = -4/15
50 = x^2 - 9x + 14
x^2 - 9x + 14 - 50 = 0
x^2 - 9x - 36 = 0
(x - 12)(x + 3) = 0
x - 12 = 0
x = 12 <==
x + 3 = 0
x = -3......not this one
