F(x) = -3x^2 - 6x - 6
(-1,-3)....x = -1 and f(x) = -3 (f(x) is the same as y)
-3 = -3(-1^2) - 6(-1) - 6
-3 = -3 + 6 - 6
-3 = -3 (correct)
yes, it is a solution
4ft x 4ft x 2ft =32
3ft x 8ft x 2ft = 48
32+48=80
Answer: 40°
<u>Step-by-step explanation:</u>
There are 4 pink angles (labeled as "a") and each are the same measure.
There are 4 green angles (labeled as "b") and each measure 50°.
A circle is 360°
4a + 4b = 360
4a + 4(50) = 360
4a + 200 = 360
4a = 160
a = 40
