You divide 18 with 3 and is going to equal 6 so that should be your constant proportionality
16+24xy+9y2 that is what I got
Answer:
14/20 or simplified 7/10 it can also be shown as 70% or 0.7 or 0.70
Step-by-step explanation:
For #19 part A :
By vertical angles and then same side interior angles 3x + 2x = 180
5x = 180
x = 36
For #19 part B:
You are correct with the 35, but you missed the fact that the 105 angle is supplementary with the unknown angle inside the triangle. So:
180 - 105 = 75
Then:
180 = 35 + 75 + x
180 = 110 + x
x = 70
Last question:
Do you know what the symbol means? Text me and tell me and I can answer it for you. :)
