Answer:
Step-by-step explanation
Note that if x>2, then x+3>3+2=5. Then x+3>0. Recall that the absolute value function is defined as


Since x+3>0, we have that |x+3|=x+3

Answer:
Two angles can be vertical and supplementary only if they add up to 90 degrees because there perpendicular.
Step-by-step explanation:
Perimeter= 2(length+width)
60= 2(l+w)
l=2w
Substitution method
60= 2(2w+w)
60= 2(3w)
30= 3w
10= w
Plug the value of w in.
l= 2(10)
l=20
Final answer: Length= 20, width=10
