Polygon ABCD has sides with these lengths:AB, 5 units; BC , 4 units; CD,4.5 units, and AD 7 units, the slope of AB is 5, the slope of BC is 0.25, the slope of CD is -2, and the slope of AD is 0. The polygon is dilated from point A by a scale factor of 1.2 to form polygon A’B’C’D. Match the slopes and lengths of the sides of the polygon A’B’C’D to their values

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!

it has changed from the width and the height.
