The question is, "how many ways ...". 

There are as many ways to solve a math problem as you can think of. (Some are shorter or easier than others.)

Essentially, an infinite number.

Answer:

3a-3b-5c

Step-by-step explanation:

((3a-3b)²-(5c)²)÷(3a-3b+5c)=((3a-3b-5c)(3a-3b+5c))÷(3a-3b+5c)=3a-3b-5c

Solve the following system: y = x 3 4x y = 18 (6, 3) (3, 6) (â’3, 6) (3, â’6).
Nastasia [14]

The solution of the given equation is (3,6). The correct option is B.(3,6)

<h3>Given equations,</h3>

y=x+3.......(1)\\4x+y=18.....(2)

<h3>How to solve the equations?</h3>

putting the value of y from equation (1) in equation (2) , we get

4x+x+3=18\\5x=18-3\\5x=15\\x=3

substitute the value of x=3 in equation (1) we get,

y=3+3\\y=6

Hence, the solution of given equation is (3,6).

So, the correct option is B.

Solve the triangle. Round your answers to the nearest tenth.
butalik [34]

The missing information of the triangle is C = 63°, b ≈ 28.084 and c ≈ 25.084. (Correct choice: C)

<h3>How to determine the missing sides and angles</h3>

In this question we have a triangle with a known <em>side</em> lengths and two known <em>angle</em> measures. First, we find the missing angle by <em>Euclidean</em> geometry:

C = 180° - 94° - 23°

C = 63°

Lastly, we determine the <em>missing</em> sides by law of sines:

b = 11 \times \frac{\sin 94^{\circ}}{\sin 23^{\circ}}

b ≈ 28.084

c = 11 \times \frac{\sin 63^{\circ}}{\sin 23^{\circ}}

c ≈ 25.084

The missing information of the triangle is C = 63°, b ≈ 28.084 and c ≈ 25.084. (Correct choice: C)
