Step-by-step explanation:

I am going with A12x + 7yx = # of adult and y = # of childrenadults cost 12 and children cost 7 <

B doesn't make much senseu could say x was for girls and y for boys...but u already know how many there areso I am not sure what the x and y could stand for.

C does't make much sense eitherx would have to be red marbles and y would have to be green marbles...but just like B, u already know how many there areso not sure what x and y could stand for

D. wrongbecause the box containing x 7 oz packages and y 12 oz packages12x + 7yfor this one to be correct, it would have to have x 12 oz packages and y 7 oz packages

step-by-step explanation: ; )

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
