6(2y - 1) - 4y simplified is 8y-6
Answer:
5π/3 radians
Step-by-step explanation:
The central angle for arc CBD has the same measure as the arc:
300° = 5π/3 radians
_____
180° is π radians, so (5/3)(180°) = 300° = (5/3)π radians.
Answer:
4x² + 13x + 3 and 2x² - 3x - 17
Step-by-step explanation:
(a)
f(x) + g(x)
= 3x² + 5x - 7 + x² + 8x + 10 ← collect like terms
= 4x² + 13x + 3
(b)
f(x) - g(x)
= 3x² + 5x - 7 - (x² + 8x + 10)
= 3x² + 5x - 7 - x² - 8x - 10 ← collect like terms
= 2x² - 3x - 17
