2n=n-5 subtract n from both sides
n=-5
check...
2(-5)=(-5)-5
-10=-10
B and c, anything with an x^2 term is a quadratic.
Answer: RQS= 90, QRS= 43, QSR= 47
Solving Steps:
180-90=90 (all the angles combined equal 180)
9x-2+10x-3=90
19x-5=90
19x=90+5
19x=95
x=5
9(5)-2= 43
10(5)-3= 47
Neither...
205/1000 equals .205
they're both kinda the same.
Hope you'll get an A
