9b≥ -18
Step-by-step explanation:
Answer:
104°
Step-by-step explanation:
In the diagram we see
Angle PRT + Angle TRS = Angle PRS
<h3>So according to the question</h3>


So ,
Angle PRS = 104°
Something to the third power would mean you are cubing something... So should it be B?
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
