There are 58 students in a classroom with 7 tables. If 8 students can sit at a table, how
many students cannot sit down at tables?

8x7=56, so 56 students can sit at a table, 58-56=2 students without a table.

Your answer would be 2.

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.
