The calculate the area, you just need to use the formulas for the shapes

Step-by-step explanation:

j: area= 36

k: area= 72

l: area= unable to solve due to not having both bases.

Step-by-step explanation:

I used the formula : ((a+b)/2)*h

then, I plugged in the numbers in the problem for the variables in the formula. Here is how I solved j:

((a+b)/2)*h = ((5+7)/2)*6 = (12/2)*6 = 6*6 = 36

I solved k the same way but with different numbers because the problem provided different bases and a different height.

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!
