Which is equivalent to the following expression (3m^2+2mn-n^2)+(m^2+4mn-n^2)

Answers

Answer 1

Answer:

Based on the available information, the expression (3m² + 2mn - n²) + (m² + 4mn - n²) is equivalent to 4m² + 6mn - 2n².

How the equivalent expression is determined?

To simplify the expression (3m² + 2mn - n²) + (m² + 4mn - n²), we can combine like terms.

Like terms have the same variables and the same exponents.

Let's group the like terms together:

(3m² + m²) + (2mn + 4mn) + (-n²- n²)

Combining like terms within each group, we get:

4m² + 6mn - 2n²

Therefore, in this case, it is concluded that the expression (3m² + 2mn - n²) + (m² + 4mn - n²) is equivalent to 4m² + 6mn - 2n².

Answer 2

Answer:

Answer:

4m² + 6mn - 2n²

Step-by-step explanation:

$(3m^2+2mn-n^2)+(m^2+4mn-n^2)\n\n=3m^2+2mn-n^2+m^2+4mn-n^2\qquad\text{combine like terms}\n\n=(3m^2+m^2)+(2mn+4mn)+(-n^2-n^2)\n\n=\boxed{4m^2+6mn-2n^2}$

g Indicate whether the sequence is increasing, decreasing, non-increasing, or non-decreasing. The sequence may have more than one of those properties The nth term is 1/n.

Answers

Answer:

decreasing, non-increasing

Step-by-step explanation:

The sequence is ...

1, 1/2, 1/3, 1/4, ...

Each term is smaller than the one before it, so the sequence is decreasing (also, non-increasing).

The formula for the length of the hypotenuse in a right triangle is squared a^2+b^2 where a and b are the lengths

Answers

Answer:

the hypotenuse in a right triangle formula is c= sqrt(a^2+b^2)

Step-by-step explanation:

The original Pythagorean's theorem equation is a^2+b^2=c^2 which we can take the square root of to isolate and solve for the equation for just the hypotenuse length. This of course is assuming that a and b are the legs of the triangle. Let me know if this wasn't what you were asking or if you need more clarification and I'll amend my answer
