X^{2m+n} * x^{n-m} / x^{m+2n}

Mathematics

Alik [6]4 years ago
7 0

Answer:

\boxed{1}

Step-by-step explanation:

x^{2m+n} * x^{n-m} / x^{m+2n}

When bases are same for exponents in division, subtract exponents.

x^{2m+n} * x^{n-m-(m+2n)}

x^{2m+n} * x^{n-m-m-2n}

x^{2m+n} * x^{-n-2m}

When bases are same for exponents in multiplication, add exponents.

x^{2m+n+-n-2m}

x^{2m+0-2m}

x^0

Any base with power or exponent of 0 is 1.

x^{0}=1

The shorter sides of an acute triangle are x cm and 2x cm. The longest side of the triangle is 15 cm. What is the smallest possi
Veronika [31]

The longest side in the triangle is opposite to the largest angle of this triangle. If triangle is acute, then all angles are acute. Acute angle has cosine that is positive.

Use cosine theorem to determine the cosine of the largest angle:

15^2=x^2+(2x)^2-2\cdot x\cdot 2x\cdot \cos \alpha, where \alpha is the largest angle.

Then

225=x^2+4x^2-4x^2\cos \alpha,\\ \\\cos \alpha=\dfrac{225-5x^2}{-4x^2}=\dfrac{5x^2-225}{4x^2}.

Since \cos \alpha>0, then

\dfrac{5x^2-225}{4x^2}>0\Rightarrow 5x^2-225>0.

Divide this inequality by 5:

x^2-45>0,\\ \\(x-3\sqrt{5})(x+3\sqrt{5})>0,\\ \\x\in (-\infty,-3\sqrt{5})\cup (3\sqrt{5},\infty).

Note that 3\sqrt{5}\approx 6.71, then the smallest possible whole-number value of x is 7.

Answer: correct choice is B

pishuonlain [190]

Answer:

A and C

Step-by-step explanation:

Since it is isosceles two sides should be equal and we already know the perimeter is 21in.

<em>5</em>+<em>5</em>+11=21in

5+<em>8</em>+<em>8</em>=21in
