2(x-6)+5=20,
2x-12+5=20,
2x-7=20,
2x=27
x=27/2
OR
x= 13.5
Answer:
x=7.5
Step-by-step explanation:
To show that the triangles are similar, we simply need to show that all sides are proportionate.
So, we create a proportion
Then we plug in the values
and can be simplified to , so that is our ratio of similarity
then we know
Now solve
1. Cross multiply
2×(2x-5) = 22
2. Distribute
4x-8 = 22
4x=30
x=7.5
There is your answer, x=7.5
Hope this helped.
You would put parentheses like this. 15-(3X4)+9=12
