In △ABC the points M and N belong to the sides AC and AB respectively. AM= 1/3 AC, AN= 1/3 AB, BC=15. Find MN

Oliga [24]

$Answer: \\ We \: have \: \frac{AM}{AC} = \frac{1}{3} , \frac{AN}{AB} = \frac{1}{3} ,\hat{A} \: is \: a \: shared \: angle \\ \Rightarrow \bigtriangleup AMN \cong \bigtriangleup ACB \\ \Rightarrow MN = \frac{1}{3} BC = \frac{1}{3} \times 15 = 5$

Simplify (4x^3+13x-7) -(6x^2+9x+2)

svetoff [14.1K]

$(4x^{3}+13x-7)-(6x^{2}+9x+2)\\\\=4x^{3}+13x-7-6x^{2}-9x-2\\\\=4x^{3}-6x^{2}+(13-9)x+(-7-2)\\\\=4x^{3}-6x^{2}+4x-9$

Answer:

Please let me know if my calculations were incorrect. I am very sorry but unfortunately, your answer will be negative and not a whole number. None of the answers fit. It is either that I made a mistake or there is something wrong with the question.

Step-by-step explanation:

$\frac{103*10-5*1010}{106} \\\frac{1030-5050}{106} \\\frac{-4020}{106} \\\\\frac{-2010}{53}$
