Bo is buying a board game that usually costs b dollars. the game is on sale and the price has been reduced by
18
which of the following expressions could represent how much bo pays for the game?
choose 2 answers

B - 0.18B

0.82B

Step-by-step explanation:

If B is the price of the board game, then the discount will be:

B * 18/100

= B * 0.18

= 0.18B

The expression for the cost Bo will pay for the game is:

B - 0.18B => Original price - discount

The expression can also be written as: (after solving)

0.82B ..

3. parallelogram

step-by-step explanation:

we turn each of our sides into direction vectors

ab=b-a=(3 - 7, 1 - 0) = (-4, 1)

bc=c-b=(1,6)

cd=d-c=(4,-1)

da=a-d=(-1,-6)

we see how the opposite sides have negated direction vectors; this is characteristic of a parallelogram.   we have congruent sides ab=cd and bc=da with unequal lengths because 1^2+6^2 is different from (-4)^2+1^2.   so it's not a square or a rhombus.  

we check the dot product of direction vectors of adjacent sides.   we have

ab dot bc = -4(1) + 1(6) = 2

that's not zero so the sides are not perpendicular.   we've ruled out rectangle.

the direction vectors indicate two pairs of congruent parallel sides, so we choose parallelogram over trapezoid.

is it 35
