Int 1 Unit 3 Summative Review: Transformations and Expanding Polynomials
Write the area of each rectangle as a product equal to its area as a sum. Combine like terms
when possible.
1.
2. For each multiplication expression, sketch an area model. Label the dimensions and the area of
each part. Then write an equation showing that the area as a product equals the area as a sum.
a.
(x-2)(2x+4)
b.
4(2x-3)
c. (3x+1)(-x+5)
3. Plot ABC on the graph with vertices A(-4,5), B(-1,4), and C(-6,2).
A.
is rotated about the origin 90° clockwise to become
and name the coordinates of A’, B’, and C’.
B.
is translated using the rule (x,y) (x+3, y+2) to become
figure and name the coordinates of A”B”C”.
Draw the rotated figure
. Draw the translated
4. Simplify each expression. Do not use negative exponents in your expression.
