Step-by-step explanation:
you cant add 1 to 5x, so subtract 1 on both sides leaving you with 1 + 5x < 4 that equals 5x < 3 -1 -1
then divide 5 from both sides 5x < 3 This leaves 5 5
you with x < 3/5
Step-by-step explanation:
use Pythagoras theorem,


The answer is 31
29 - 13 is 16
16 + 15 is 31
Simplified would be 4xy + 3x^2 + 6x
