Answer:

18m³ + 2m² – m

Combine (add and subtract) the terms that have the same variable and exponent. Do not combine terms that have different exponents or variables.

5m³ +5m³ + 8m³ = 18m³

3m² +3m² –4m² = 2m²

–2m –2m +3m = –m

Step-by-step Solution:

Simply change the denominators such that both denominators are the same. Then, add the fractions to get your result.

  • => 3 x 1/2 x 3 + 1/6
  • => 3/6 + 1/6
  • => 4/6 = 2/3

Use set notation to write the members of the following set, or state that the set has no members. Odd numbers between 2 and 82 t
adell [148]

Let the set of all Odd multiples of 9 between 2 and 82 be denoted by D, then, using set-builder notation,

D=\{ 18n+9 \mid n \in \mathbb{N}, 0\le n\le 4 \}

The odd multiples of 9, m, in the range 2\le m \le 82 form the set

\{9,27,45,63,81\}

Each member of the set is a term of the arithmetic progression

U_n=18n+9

where the values of n range from 0 to 4, or 0\le n\le 4

Putting these facts together, we get the result

D=\{ 18n+9 \mid n \in \mathbb{N}, 0\le n\le 4 \}
