B. 10x^3 + x − 1

C. 2x^3 + 15x + 6

D. 10x^3 − x − 1

The Correct

B. 10x^3 + x - 1

I really hate to beg, but I need brainlest points to rank up, so if you might, please award brainliest to me! I hope this helps!!

after simplifying it i got: -36.25 as my answer. hope that !

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.
