I would say A. I'm assuming this is to do with the equation y=kx, therefore A has the k value of -12
Answer:
Step-by-step explanation:
Area of a square = pie r^2.
Radius = sqrt 484 = 22.
Diameter = 2 r = 2 x 22 = 44.
Hope this helps!

Answer:
Area of ΔPQR = 25 units
Step-by-step explanation:
We will use the following formula to calculate the area of triangle ΔPQR:
A = 1/2 | x₁(y₂-y₃) + x₂(y₃-y₁) + x₃(y₁-y₂) | = 1/2 |(-6(1+3) +2(-3-7) +(-1)((7-1)| =
A = 1/2 |-6 · 4 + 2 · (-10) + (-1) · 6| = 1/2 | -24-20-6| = 1/2 | -50| = 1/2 · 50 = 25
A = 25 units
God with you!!!
