Which is the LCM of (x + y) and (x + y)2.

(x+y)²

Step-by-step explanation:

Given the expressions (x + y) and (x + y)².

We are to find the LCM of (x + y) and (x + y)²

Taking the factors as shown

(x+y ) || (x + y) (x + y)²

(x+y ) || 1   (x+y)

        ||  1     1

Multiplying both factors to get the LCM

= (x+y)(x+y)

= (x+y)²

Hence the LCM of (x + y) and (x + y)² is  (x+y)²

b. x- 48 =120

step-by-step explanation:

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
