the degree of polynomial is 3.
The expression would show three sevenths of y minus four.
You would do 13 divided by 7 which is 1.8571, but you have to simplify, to the nearest hundredth. So 7 is greater than 5 so the answer would be $1.86
The angles don’t change since the triangle was dilated by a factor
X=30
Y=60
Z=90
.8 is your answer. Because you can’t evenly divide ten into eight, you have to add a decimal then add a 0 behind the eight. 10 goes into 80 8 times evenly, so your answer is .8 (Sorry if it was confusing, but I hope the answer helps!)
