What is the value of the expression r2 plus s3 when are equals 2 and s equals 3?
2 squared is 4 3 cubed is 27 27 plus 4 is 31
What is 2 squared times 3 cubed?
Well, honey, 2 squared is 4 and 3 cubed is 27, so when you multiply them together, you get 108. So, there you have it - 2 squared times 3 cubed equals 108. Math can be a piece of cake when you break it down!

The sum of three consecutive odd integers is 5 less than twice the smallest of these integers?
Let the inegers be x+1, x+3, and x+5, these are 3 consecutive odds, we could have used x and x+1 and x+3, if x was odd Now the next part is often confusing. So let's say the sum was S, we have S=2(x+1)-5. Now, S= 3x+9 So we have 3x+9=2x+2-5 or x=-9-5+2 so x=-12 x+1=-11 which is odd x+3=-9 x+5=-7 The sum is -27 -27=2(-11)-5 So to see for usre if this works.. our sum is -27 and that is 5 less than twice -11 which is -22. That is to say -27 is 5 less than -22. Would this work with the positive integers 7, 9, and 11? The sum is 27 and the smallest is 7, but 27 does not equal 14-5, so no.
How can you draw a square with a area of 9 sq cm?
Well, darling, to draw a square with an area of 9 sq cm, each side would have to be 3 cm in length. So grab your ruler, draw four sides that are 3 cm each, and voilà, you've got yourself a 9 sq cm square. Just make sure those sides are straighter than my martini! Cheers!
