Answer:
4
Step-by-step explanation:
40/10=4
Your answer would be 22 because it says <em>"sum"</em> which means <u>add.</u> Then it says "<em>of three consecutive <u>even</u> numbers</em>" which means you're going to be adding <u>three</u> of the <em>same <u>even</u> number </em>to get 66. 22 is an <u>even</u> number, so let's try it out: 22 + 22 + 22 = 66. (You can also divide 66 by 3.) 22 is the cOrrect answer.

Answer:
82°
Step-by-step explanation:
m÷ BAD + m÷ BCD = 180°
98° + m÷BCD = 180°
m÷BCD = 180° - 98°= <u> </u><u>8</u><u>2</u>°
7
You divide 28 by 4 and get 7. Then you divide 49 by whatever you get.
(2x - 1)(x + 2y - 3) =
2x(x + 2y - 3) + (-1)(x + 2y - 3) =
2x^2 + 4xy - 6x - x - 2y + 3 =
2x^2 + 4xy - 7x - 2y + 3
