Draw pascal's triangle with the number of rows required to expand the expression (2x^3+3y^2)^7

1

1,2,1

1,3,3,1

1,4,6,4,1

1,5,10,10,5,1

1,6,15,20,15,6,1

1,7,21,35,35,21,7,1

I did it for you

go on the tube you might find some information there

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.
