Answer:
x=14
Step-by-step explanation:
to find x you have to isolate it so you divide 3 by both sides and that leaves you with the answer
It’s 10 it has it near the dot
Answer:
B. 12
Step-by-step explanation:
✔️Find the value of x
The side lengths of two similar triangles are always proportional.
Given that ∆ABC ~ ∆LMN, therefore:

AB = 5
LM = 10
AC = x + 5
LN = 3x + 3
Plug in the values

Cross multiply

(distributive property)
Collect like terms
Divide both sides by 5
x = 7
✔️Find AC
AC = x + 5
Plug in the value of x
AC = 7 + 5
AC = 12
Answer:
B. X squared is -3 times -3, which is equal to 9.
