Answer:
The answer to your question is: AC = 36
Step-by-step explanation:
Data
Segment AC with midpoint = B
AC = 5x - 9
AB = 2x
AC = ?
Process
total length = AC but B is the midpoint so AB + AB = CA
2AB = CA
Substitution 2(2x) = 5x - 9
4x = 5x - 9
Solve for x 4x - 5x = -9
-1x = -9
x = -9/-1
x = 9
Finally, AC = 5x - 9
= 5(9) - 9
= 45 - 9
= 36
Answer:
13
Step-by-step explanation:
- x × (x + 9) = x² + 9x = 286
- x² + 9x - 286 = 0
- (x - 13)(x + 22)
- x = 13 or -22
- Since you cannot have negative length, it’s 13
Answer:
2x² + 19x + 45
Step-by-step explanation:
(x + 5)(x + 1) + (x + 5)(x + 8) ← expand both sets of factors using FOIL
= x² + 6x + 5 + x² + 13x + 40 ← collect like terms
= 2x² + 19x + 45
