Manuel created a factor tree and wrote the prime factorization of 60 shown below.60^4 15 ^ 3 5what is manuel’s error?

He did not include 15 in the prime factorization.

Step-by-step explanation:

thus, the first answer choice, y = sec x, is the correct one

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
