Answer:
- 3x² + x + 5
Step-by-step explanation:
g(x) + f(x)
= 4x + 5 - 3x² - 3x ← collect like terms
= - 3x² + x + 5
Answer:
B
Step-by-step explanation:
Answer/Step-by-step explanation:
x + 74° + 20° = 180° (sum of interior angles of a triangle)
x + 94° = 180°
x = 180° - 94° (subtraction property of equality)
x = 86°
y = 74° + 20° (exterior angle theorem of a triangle)
y = 94°
y + z + 32° = 180° (sum of interior angles of a ∆)
Plug in the value of y
94 + z + 32 = 180
z + 126 = 180
z = 180 - 126
z = 54°
