1. CCSS 8 Review for Homework Quiz Solving Equations: 4.4-4.6
Have your three homework papers out on your desk to use on the quiz, and to help review for the quiz.

2. Notice this is a rectangle with a triangular region cut out of it.
Find the area of the shaded region in the figure. (#15 from “Lesson 3.5 Practice”)
Area of rectangle = bh
A = (13)(16)
A = 208 ft2
Area of a triangle = ½bh
A = (½) (13)(16)
A = 104 ft2
Area of the shaded region =
area of the rectangle – area of the triangle
Shaded area = 208 – 104
= 104 ft2
16 ft
13 ft
Notice this is a rectangle with a triangular region cut out of it.

3. Solve the equation. (#8 from 4.6)
−3 𝑐−8 −5=9 𝑐+2 +1
-3c + 24 – 5 = 9c
-3c = 9c + 19
-9c c
-12c = 19
-12c = 0
c = 0
