What is the length of AC?<br><br><br> 3 ft<br><br> 4 ft<br><br> 9 ft<br><br> 18 ft
iragen [17]

Answer: The length of AC is 18 ft.

Step-by-step explanation:

By the given diagram,

AM = MB and CN = NB

M and N are the mid points of the sides AB and CB respectively,

Thus, by the mid point theorem,

MN ║ AC,

By the alternative interior angle theorem,

∠BMN ≅ ∠BAC

∠BNM ≅ ∠BCA

Thus, by AA similarity postulate,

ΔBMN ≅ ΔBAC

By the property of similar triangles,

\frac{BM}{BA}=\frac{MN}{AC}

\frac{BM}{BM+MA}=\frac{MN}{AC}

\frac{4}{4+4}=\frac{9}{AC}

\frac{4}{8}=\frac{9}{AC}

4AC=72\implies AC = 18\text{ ft}

Thus, The length of AC is 18 ft.

For which equation is  not a solution? x=-1/3
aniked [119]
The answer is B. 
We can prove this by putting -1/3 into x. 
6(-1/3) - 5 = 7 
Multiply -1/3 by 6. 
-2 - 5 = 7 
Subtract 5 from -2. 
-7 \neq 7 
So, -1/3 is not a solution to this equation. 
Hope this helps!
