Mild: Which expression is equivalent to $$\left(x+2\right)\left(3x-3\right)$$ ? NO CALCULATOR

Medium: The perimeter of the triangle shown is $$8x-6$$ .

Which expression represents the length of QR? Calculator OK

Spicy: A rectangle has a perimeter of 64.

-Let x equal the width of the rectangle

-Let y equal the area of the rectangle

Which equation could be used to find the area of the rectangle?

Spicy: David has a rectangle and a right triangle.

• The length of the rectangle is 5 more than its width, w.

• The length of the shorter leg of the triangle is equal to the rectangle’s width.

• The length of the longer leg of the triangle is twice the length of the rectangle.

Which function, f(w), represents the combined area of the rectangle and the triangle? (Hint: Recall that $$A_{Triangle}=\frac{1}{2}bh$$ ) Calculator OK
