1. Which one of the following formulas will find the sum of interior angles of a polygon with n sides? (1 point) 180(n − 2)

180(n − 360)

180(n − 1)

180n

2. If ABCD is a parallelogram, which of the following statements must be true? (1 point)

∠A ∠B and ∠C ∠D

AB = BC = CD = AD

AC = BD

AB = CD and BC = AD

3. Fill in the blank with always, sometimes, or never. If there is not enough information, choose

inconclusive.

A quadrilateral has one pair of parallel sides.

(1 point)

sometimes

never

inconclusive

b) the dogs need to shift their focus to human scent.

use the power rule  

( a b ) n = a n b n

to distribute the exponent.

apply the product rule to  

3 x 2 y 3 . ( 3 x 2 ) 2 ( y 3 ) 2

apply the product rule to  

3 x 2 . 3 2 ( x 2 ) 2 ( y 3 ) 2

raise  

3

to the power of  

2 . 9 ( x 2 ) 2 ( y 3 ) 2 multiply the exponents in   ( x 2 ) 2

.

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 2 ⋅ 2 ( y 3 ) 2

multiply  

2   by   2 . 9 x 4 ( y 3 ) 2

multiply the exponents in  

( y 3 ) 2 .

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 4 y 3

⋅

2

multiply  

3   by   2 . 9 x 4 y 6
