You can just use a calculator unless you need to show your work
Answer:
Step-by-step explanation:
angle A = 40
angle B = 60
angle C = we don't know.
A + B + C = 180
C = 180 - A - B
C = 180 - 40 - 60
C = 80
40 + 60 + 80 = 180
180 = 180...It checks!
5(2x+1) (2x-1) is what you get when you factorise this equation
Treat each of the rings as a point on a graph the point being (carat, Cost ring)
Knowing this we have 2 points which we need to form a line.
(0.3, 3457); (0.5, 4373) From this we can for a slope and then an equation.
slope =
