First, you need to collect the like terms; 7x + (-20 - 90). Next simplify; 7x - 110
answer; 7x - 110
Distribute each term in one parenthesis to the other terms in the other parenthesis.
(x - 2) (2x + 3)
First, distribute x. When distributing, multiply
x(2x) = 2x²
x(3) = 3x
Next, distribute the other term, -2. Remember to change the signs.
-2(2x) = -4x
-2(3) = -6
-------------------------------------------------------------------------------------------------------------------
2x² + 3x - 4x - 6
Combine like terms
3x - 4x = -x
2x² - x - 6
-------------------------------------------------------------------------------------------------------------------
2x² - x - 6 is your answer
hope this helps

Answer:
7 classmates
Step-by-step explanation:
The last person in the line is in position 35.
The Maria's leading classmate is in the position 35-23+1 = 13.
So, Maria's classmates are from position 13 to 19 (not including herself), and their number is 19-12 = 7 persons.
ANSWER. Maria has 7 classmates (not including herself).
Hope this helps.
