Question 7. A student is called on to expand (x + 4) using the binomial theorem. Here are the steps they took to do so.
Step 1: List out the coefficients from
Pascal's Triangle.
P(x) = 1+3+3+1
Step 2: Multiply each term by the
descending powers of x.
P(x) = 1 (x3) +3(x2) +3(x2) +1 (30)
Step 3: Multiply each term by the
ascending powers of 4.
P(x) = 1(x3)(40) +3(x2)(41) +3(x1)(42) +1(x0)(43)
Step 4: Simplify the coefficients. P(x) = x3 + 12x2 + 16x +64
Which of the steps was applied incorrectly and affected the final result?
A) Step 1
B) Step 2
C) Step 3
D) Step 4

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363

22, 28, 34, 40, 46

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

(1)   (2)   (3)   (4)   (5)   (6)   (7)   (8)   (9)   (10) (11) (12) (13) (14)

22 | 28 | 34 | 40 | 46 | 52 | 58 | 64 | 70 | 76 | 82 | 88 | 94 | 100

i don't see any steps below, sweetheart
