Can someone help me pls?

2) 22in.squared 3) 28in.squared 4) 17 1/2in. squared or 35/2in. squared

Step-by-step explanation:

The one picture is of the formula you use to solve it. See in the case of problem 2.) ,

For number 3) ,

Plug these values into the formula A=1/2 × h (a+b)

Always do a+b first (since they are in parenthesis) and then multiply that by h and 1/2.

Here is the process in the other picture.

It is quite simple once you practice more! The third picture is for you to do and see if you get the same answer I did.

I hope you found what you needed!

yeah and the opposite of cheating is studying ( you should try it some time)

step-by-step explanation:

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!
