I'm guessing the total amount of degrees is 360 degrees.
67 + 130 + 72 = 269
360 - 269 = 91
Answer = 91°
Hope this helped☺☺
Answer:
7x (x + 1 ) ( x + 3 )
Step-by-step explanation:
7x³ +28x² +21x
7x ( x² + 4x + 3 )
7x [ x² + 1x + 3x + 3 ]
7x [ x ( x + 1 ) + 3 ( x + 1 ) ]
7x (x + 1 ) ( x + 3 )
Hi there!

f(x) = -3x² + 11x + 37
Substitute in 4 for x to find f(4):
f(4) = -3(4)² + 11(4) + 37
f(4) = -3(16) + 44 + 37
f(4) = -48 + 44 + 37
f(4) = 33
3 divided by 4 subtract 9 divided by 12 equals 0. Hope this helps
