Answer:

36.

Step-by-step explanation:

sec^2 (π/9) = 1 / cos^2 (π/9) = 1.13247

sec^2 (2π/9) = 1 / cos^2 (2π/9) = 1.70409

sec^2 (4π/9) = 1 / cos^2 (4π/9) = 33.1634

Adding these gives us  36 to the nearest whole number

(6x+2)^2=36x^2+Bx+4 How Would You Answer That. I'm Not That Good At Algebra.
Verizon [17]

Let's multiply out the equation 6x+2 times 6x+2 using the square. Draw a 2 by 2 bow and put the equation across the bottom and verically. Multiply across to get this. 6x times 6x =36x^2 6x times two =12x do it again and get 12x. 2*2=4. That means x would equal 24.
