Answer: B. X<12
Step-by-step explanation:
First we need to find out what number multipled by 4 is less than 56
4 x 12 = 48
56-48 = 8
And 4 is lower/less than 12 so that's why it's B
Answer:
yes
Step-by-step explanation:
yes they are correct
The denominator( s ) we are given are
, and . The first thing we want to do is factor the expressions, to make this easier -

This expression is a perfect square, as ( x )^2 = x^2, ( 2 )^2 = 4, 2 * ( x ) * ( 2 ) = 4x. Thus, the simplified expression should be the following -

The other expression is, on the other hand, not a perfect square so we must break this expression into groups and attempt factorization -

Combining ( x + 2 )^2 and ( x + 2 )( x + 3 ), the expression that contains factors of each is ( x + 2 )^2 * ( x + 3 ), or in other words the LCM.

Ok now that i understand the question better i say it is D
