What is the intermediate step in the form (x+a)2 = b as a result of completing the square for the following 5x^2-360=-60x

4 adults and 12 babies

step-by-step explanation:

4 x 7 = 28

12 x 15 = 180

180 + 28 =208

4 x 3 = 12

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6

43

step-by-step explanation:

not sure if this is supposed to be a trick question. 43 is the only one that makes any sense.
