Three gallons of gas cost $6.48. How much do 7 gallons cost?

$45.36

Step-by-step explanation:

you multiply 6.48 by 7 and your answer is $45.36

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.
