A rectangular pyramid is cut
vertically by a plane
as shown in the
figure. Which
two-dimensional
shape will you get?

answer: no

step-by-step explanation:

you are only given the cost not the amount of pounds.

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.

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

9x
