-3 + 42 > 3

x > 15
x < 15
x > 13
x < 13

Where's the x?

I am assuming that the problem must be

-3 + 42 > 3x

if that is true, then

x < 13.

As this statement is, -3 + 42 > 3 is a true statement because -3 + 42 = 39, and

39 > 3 [39 is always greater than 3]

Let me know if you need a step by step.

D) x < -15

Step-by-step explanation:

-3x - 42 >3

Add 42 to each side

-3x - 42+42 >3+42

-3x > 45

Divide each side by -3.  Remember to flip the inequality since we are dividing by a negative

-3x/-3 < 45/-3

x < -15

not really sure how you want this solved but the equation itself is true

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.
