Answer:
√15
Step-by-step explanation:
Because x is an altitude, the largest triangle is similar to both the triangle on the left half and the triangle on the right half.
The ratio of 3 to x is equal to the ratio of x to 5 (because the triangles are similar, as stated earlier)
You write the following equation to represent it:
, which (when the denominators are multiplied) results in:
Which makes x = √15
9.
|2x+6|-4=20
or,|2x+6|=24
or,2x=24-6
or,x=18/2
x=9
Answer: no because 13(6+y) is 78+ 13y
