Help pls I don’t understand this question?

C

Step-by-step explanation:

For the lines to be parallel, then x - 20 and 52 would be alternate angles and congruent, so

x - 20 = 52 ( add 20 to both sides )

x = 72

c!

Step-by-step explanation:

You have to multiply the numbers in the sections and see which one is the same product as 52. So, 72 x 20= 58! hoped it helped!!

i know the answer is 3

step-by-step explanation:

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
