Algebraic fractions are the same as normal fractions, but they have algebraic expressions as the numerator/denominator. 

For example, \frac{2}{7} is a normal fraction, but \frac{3y - 2x}{2y + 5x} is an algebraic fraction.

Option B:

Law of cosine, two sides and the included angle are known.

Solution:

Let us first know the law of cosines and law of sines.

Law of cosine:

If we know the sides a, b and the included angle θ, then we can find the third side c. This is known as the law of cosine.

c^2=a^2+b^2-2abcos\theta

Law of sine:

The sides of a triangle are to one another  in the same ratio as the sines of their opposite angles.

$\frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC}

Given ∠P and the sides r, q are known.

<u>To find the value of p:</u>

Option A: Law of cosines, all sides are known.

It is false by the above definition of law of cosine.

Option B: Law of cosine, two sides and the included angle are known.

It is true by the above definition of law of cosine.

Option C: Law of sines, all sides are known.

It is false, because one angle is given in question.

Option D: Law of sines, two angles and the included side are known.

It is false, because two angles are not given.

Option B is the correct answer.

Hence the answer is "Law of cosine, two sides and the included angle are known".

For all values of x, which expression is equivalent to 4(5x + 3) - 4x?
kaheart [24]
4(5x + 3) - 4x
4*5x = 20x
4 * 3 = 12
20x and 4x are like terms,so 20x - 4x=16x
12 doesn’t have anything to go with,so it just stays

16x + 12 (B is the correct answer)
