Which of the following expressions are equivalent to -3(2 + 7)? Choose all answers that apply:
A) 6 + 21
B) -21 +6
C) None of the above

-3(2+7) = -27

Step-by-step explanation:

Step 1: Solve Original Equation = -27

Step 2: Solve the Rest. A) 6 + 21= 21

                                      B)  -21 + 6= -15

Step 3: None of these answers equal the original answer (-27). Therefore making it C) None of the above.

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.

b)   f(n) = 6n + 16

n = what is the number of the row ( 22 would be row 1) so if we replaced n with 1, we would get 22

c)   the 14th row will have 100 seats
