Solve for x: x - 9 = 15 a. 6 b. 24 c. -24 d. -6

X = 24

Step-by-step explanation:

Add 9 To Both Sides

X - 9 + 9 = 15 + 9

Simplify

X = 24

Best Of Luck,

- I.A. -

The answer is B. 24.

A isn't going to work, since 6 is less than 9. It'd give you a negative number.

D won't work, either, it'd give you -15. Again, you'd get a negative number.

C won't work for the same reasons as last time, it'd give you a negative number.

B gives you the exact number we're looking for, and it's a positive number.

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.
