The answer is -7.20 click on file for more details.
we know that a₁ = 1, and aₙ = aₙ₋₁ + 2, is another way of saying, we add 2 to get the next term, namely, 2 is the common difference.

The answer is C. Infinitely many because all measurements added together equals 180 degrees.
Answer:
284.24
Step-by-step explanation:
by multiplying 0.68 to 418 we get 68% of 418
Answer:
(y-(-3))=4(x-(-1))
Step-by-step explanation:
formula for point slope form is:
y-y1=m(x-x1)
just plug in numbers from the point (-1, -3) for x1 and y1. The slope 4, would plug into m.
