Answer:

B) 4(x - 3)(3x - 2)

Step-by-step explanation:

12x² - 44x + 24

4[3x² - 11x + 6]

4[3x² - 9x - 2x + 6]

4[3x(x - 3) - 2(x - 3)]

4(x - 3)(3x - 2)

The correct answer is  ∠Y = 75°
because

    45°∠A ∼ ∠X         
         ∠B ∼ ∠Y = 75°   
    60°∠C ∼ ∠Z    
  
  45 + 60 = 105   
  180 -105 = 75

The number of seats in each row of a theater forms an arithmetic sequence. The fifth row contains 22 seats. The tenth row contai
beks73 [17]

Let s_n denote the number of seats in the n-th row. s_n is arithmetic, so

s_n=s_{n-1}+d

for some constant d.

We're told s_5=22 and s_{10}=37, so that

s_{10}=s_9+d

s_{10}=(s_8+d)+d=s_8+2d

s_{10}=(s_7+d)+2d=s_7+3d

and so on up to

s_{10}=s_5+5d\implies37=22+5d\implies5d=15\implies d=3

The pattern continues:

s_5=s_4+3

s_5=(s_3+3)+3=s_3+2\cdot3

and so on up to

s_5=s_1+4\cdot3\implies22=s_1+12\implies\boxed{s_1=10}
