If we wanted to prove quadrilateral MNOP was a parallelogram, which method below would not work? 1.Doing four slope formulas to show both pairs of opposite sides are parallel.

2.Doing two midpoint formulas to show the diagonals intersect at the same point.

3.Doing two slope formulas and two distance formulas to prove the same pair of opposite sides is congruent and parallel.

4.Doing two distance formulas to show that adjacent sides are not the same length

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
