71/3=23.6
36/7=5.14
23.6-5.14=18.46
So, the correct answer is 18.46

Choose the correct sum of the polynomials (6x3 − 8x − 5) (3x3 6x 2). 9x3 − 2x − 3 3x3 2x 3 3x3 − 2x − 3 9x3 14x 3.

RUDIKE [14]

Like terms have the same variable and power. The sum of the two polynomials $(6x^3 -8x -5)+(3x^3+6x+2)$ is $3x^3 -2x -3$ .

<h3>What are Like terms?</h3>

Like terms are those terms that are having the same variables, also the variables are of the same order as well.

for example, 25x and 5x are like terms; 30xy and 7xy are like terms, 9x³ and 4x² are not like terms, etc.

We know that in order to find the sum of the two polynomials we need to add or subtract the like terms, therefore, the sum of the polynomials can be done as,

$(6x^3 -8x -5)+(3x^3+6x+2)\\\\= 6x^3 -8x -5+3x^3+6x+2\\\\= 6x^3 +3x^3- 8x+6x-5+2\\\\ = 3x^3 -2x -3$

Hence, the sum of the two polynomials $(6x^3 -8x -5)+(3x^3+6x+2)$ is $3x^3 -2x -3$ .

Triangle ABC is given where m(angle sign)A=33 Degrees, a=15 in, and the height, h, is 9 in. How many distinct triangles can be m

Mashcka [7]

Answer: You could have an infinite amount of triangles with these measurements.

Unless, you are missing something in the problem, there is not enough information that would narrow it down to a single triangle. Angle A is fixed and the height is fixed. However, Angle B and C could be anything as long as they formed a triangle and had side a of 15 in between them.

Triangle A B C is shown. Angle C A B is a right angle. Angle A B C is 30 degrees and angle B C A is 60 degrees. The length of A

scoundrel [369]

Answer:

SinB = 1/2, SinC = √3/2 and

TanC = √3

Step-by-step explanation:

The question lacks options. Find the complete question in the comment section.

Given triangle ABC, we will use the SOH, CAH, TOA trig identity to get the correct ratio.

Given the hypotenuse BC = 18 and one of the other two sides AC = 9, we can get the third side AB using Pythagoras theorem.

BC² = AC²+AB²

18² = 9²+AB²

2² = 1²+AB²

AB² = 4-1

AB² = 3.

AB = √3

Making <ABC as reference angle, AC will be opposite and AB will be the adjacent.

Sin<ABC = opp/hyp = AC/BC

Sin<ABC = 1/2

Cos<ABC = adj/hyp = AB/BC

Cos<ABC = √3/2

Tan<ABC = opp/adj = AC/AB

Tan<ABC = 1/√3

Making <BCA as reference angle, AB will be opposite and AC will be the adjacent.

Sin<BCA = opp/hyp = AB/BC

Sin<BCA = √3/2

Cos<BCA = adj/hyp = AC/BC

Cos<BCA = 1/2

Tan<BCA = opp/adj = AC/AB

Tan<BCA = √3

Frim the above calculation, the correct options are sin<ABC = 1/2, Sin<BCA = √3/2 and Tan<BCA = √3
