Answer:
3x - (2x + 5)
X represents any number so 3 times a number is 3x. and 5 more than 2 times a number is 5 plus 2x. And the difference between the two is 3x - (5 + 2x)
To add or subtract monomials<span> that are like terms, you leave the variables as they are and you add or subtract the coefficients. If you have </span>monomials<span> that are not like terms, you add or subtract as many like terms as you can and you leave the terms that are not like terms in your answer.</span>

Answer:
∠ A = 66°
Step-by-step explanation:
Supplementary angles sum to 180° thus
∠ A + ∠ B = 180 , substitute values
2x - 14 + 3x - 6 = 180 , that is
5x - 20 = 180 ( add 20 to both sides )
5x = 200 ( divide both sides by 5 )
x = 40
Thus
∠ A = 2x - 14 = 2(40) - 14 = 80 - 14 = 66°
