Find the product
–5r3(2r2 – 3r – 5)
a) –10r5 – 15r4 – 25r3
b) –10r5 + 15r4 + 25r3
c) 10r5 – 15r4 – 25r3
d) –10r6 + 15r3 + 25r3

B) –10r5 + 15r4 + 25r3

Step-by-step explanation:

–5r3(2r2 – 3r – 5)

apply distributive property:

–5r3*(2r2) –5r3*( – 3r) –5r3*(– 5)

–10r5 + 15r4 + 25r3

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.
