Answer: 11x^2+48x
---------------------------------------
Work Shown:
(x^2+43x+10) - (-10x^2-5x+10)
x^2+43x+10 - (-10x^2) -(-5x) -(10)
x^2+43x+10 + 10x^2+5x-10
(x^2+10x^2)+(43x+5x)+(10-10)
11x^2+48x+0
11x^2+48x
Answer:
I believe its 66
Step-by-step explanation:
55×20%=11
55+11=66

Answer:
It is true.
Step-by-step explanation:
congruent polygons have the exact same size and are a perfect match because all corresponding parts are congruent (equal). ... This means that if two polygons are similar, then their corresponding angles are congruent
Try this solution (this is not the only way!):
Q1: if cosx=-0.5 and x∈(90;180), it means x=120°.
So, sin(x-30)=sin(120-30)=sin90°=1.
<u>answer</u>: 1.
Q2: it tgx= -1/√3 and x∈(270°;360°), it means x=330°.
So, sin(x+30)=sin(330+30)=sin360°=0.
<u>answer</u>: 0.
