Rectangle abcd was dilated to create rectangle a'b'c'd.
what is ab?
6 units
7.6 units
9.5 units
12 units

6

Step-by-step explanation:

Let's setup a proportion to find AB.

AB corresponds to A'B'.

BC corresponds to B'C'.

So setting up proportion this would look like:

[\tex]\frac{AB}{A'B'}=\frac{BC}{B'C'}[/tex]

[\tex]\frac{AB}{15}=\frac{3.8}{9.5}[/tex]

Cross multiply:

Divide both sides by 9.5:

Put into calculator:

AB=6 so A is correct, hope this help! Branliest would be awesome :)

Step-by-step explanation:

Since the larger rectangle and the smaller rectangle are essentially the same just bigger, they will be proportionate.

Therefore..

9.5/3.8=15/AB

You can cross multiply to find AB...

9.5AB=57

Divide 57 by 9.5 to separate AB, which you can think of like x...

AB=57/9.5

AB=6

3

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!
