Step-by-step explanation:
√7 + √7 = 2√7 (irrational)
√7 + (-√7) = 0 (rational)
√7 + 0 = √7 (irrational)
√7 + 7 = 7 + √7 (irrational)
The answer is the 2nd option / -√7.

I think you have to add 513mm and 712mm to get the perimeter of your rectangle hope this helped
The equation for the stand form of a line is y = mx + b.
You will need
m = slope
b = y-intercept
The question already gave you both of those so you simply put them into the equation "y=mx+b"
m = -1/2
y-intercept = 1
Plug those into "y = mx + b"
Your equation is: y = -1/2x + 1
