Cindy says she found a shortcut for doing multiplication problems. when she multiples 3 x 24,she says,’
“3x4 is 12,or,1 ten and 2 one.” then, there’s just 2 tens left in 24,so add it up, and you get 3 tens and 2 ones.” do you think cindy shortcut works?

How can you solve an equation with a variable on both sides? complete the explanation. you can solve the equation by using *(blank)* operations to get the variable terms on one side of the equal sign and the constant terms on the *(blank)* side. then *(blank)* both sides by the coefficient of the resulting variable term.

Determine whether the quadrilateral below is a parallelogram. justify/explain your answer (this means back it up! give specific information that supports your decision. writing just "yes" or "no" will result in no credit.)

Solve each quadratic equation by factoring and using the zero product property. x^2 - 8x + 30 = 3x
