Write an inequality that represents "nine less than three times a number is greater than forty"?

Three times a number is 3n.  Nine less than that is 3n-9.  This is NOT the same thing: 9-3n.  Subtraction is not commutative.  If n was 1, for example, 3(1)-9=-6.  Looking at the other expression, 9-3(1)=6.  6 and -6 are definitely not the same number.  So be careful how you set up your expression.  Our inequality then would be

Step-by-step explanation:

step-by-step explanation:

|ab| = 1.4 = 4

h = 1.4 = 4

a(abc) area = 4.4 = 16/2 = 8

area of abc = 8 cm^2
