side = ⱱ100
side = 10cm
perimeter = 4s
= 4 x 10
=40cm

Answer:
y = -3x +5
Step-by-step explanation:
The parallel line will have the same slope: m = -3.
The new y-intercept is ...
b = y -mx
y = -1 -(-3)(2) = -1 +6 = 5
Then the equation of the parallel line through (2, -1) is ...
y = -3x +5
Yup 39 is the correct answer good job :-)
First, you would multiply 12 by two. Then, when you get that answer, subtract 5 and you will find Greg's age.
Hope this helps!:)
