Find the product of (–d + e)(4e + d). Which statements are true? Check all that apply

vlada-n [284]

(- d + e)(4e + d)
-d*4e - d^2 + 4e^2 + de
-d^2 - 3de + 4e^2

That's the answer to the expansion. Without choices, there is not much else I can do.

If you picked 41.5% of the apples on a tree, and you picked 34 apples, how many apples did the tree contain before you starting

Around 81 whole apples
34 divided by 41.5 = 0.81927711
0.81927711 x 100 = 81.9.....
So that rounded 81 whole apples and 0.9.... of an apple

It’s 81 apples
