Circle or box your answer when complete. Good job reading the directions, now write your favorite number in the right margin for a bonus point! 1) Simplify each expression by combining like terms. (Expressions & Equations; 16 points) a) 2 ! − −3 − 4 − 1 + (− ! ) + 5 − (−3) b) 6 ! + 2 + 24 − 3 − 7 ! 2) Simplify each expression by using the distributive property. (Expressions & Equations; 12 points) a) 3 5 − 7 = b) −4 + 6 = 3) Draw the original figure and the copy with the side lengths labeled. Your diagrams do NOT have to be drawn to scale. (Geometry; 15 points) a) A triangle has side lengths of 1.5 cm, 3.2 cm and 4.16cm. It is enlarged using a scale factor of three. b) What is the perimeter of the new triangle? 4) Simplify each integer expression. (Number System; 12 points) a) −33 + 7 = b) −15 − 8 = c) −12 + −6 = d) −11 −4 = e) !!" !! = f) −23 − −5 = 5) Simplify each expression using order of operations. (Number System; 18 points) a) 7 + 1 ∙ 5 − 2 ! + 6(4) b) !!! ∙ !!(!!(!!)) !! !!!! !!
