12z^2 - 7z -12/ 3z^2 + 2z - 8
= (4z+3) (3z -4)/ (z+2)(3z -4)
= (4z + 3) / (x+2)
Hope this helps
Answer:
C) f(3) = 111
Step-by-step explanation:
f(x) = 3x^3 + 8x^2 – 10x – 12
Let x=3
f(3) = 3(3)^3 + 8(3)^2 – 10(3) – 12
=3*27+8(9) -30-12
=81+72-30-12
=111
Answer: 135 Degrees
Step-by-step explanation:
There are 540 degrees in a pentagon, and we have three right angles. Three right angles measures 270 degrees, half of 540. So we have 270 degrees left, and we divide it by two since the angles are equal and get 135 degrees.
The piecewise function would be 
.
48 degrees.
Subtract 180-99 = 81
Subtract 180-129 = 51
180 - 51 - 81 = 48 degrees
