What is the product?<br><br> 1st pic is the problem<br> the rest are the answer choices
Bumek [7]

For this case we must find the product of the following expression:

(y ^ 2 + 3y + 7) (8y ^ 2 + y + 1)

We apply distributive property, which states that:

(a + b) (c + d) = ac + ad + bc + bd

So:(y ^ 2 + 3y + 7) (8y ^ 2 + y + 1) =\\(y ^ 2) (8y ^ 2) + (y ^ 2) (y) + (y ^ 2) (1) + (3y) (8y ^ 2) + (3y) (y) + (3y) (1 ) + (7) (8y ^ 2) + (7) (y) + (7) (1) =\\8y ^ 4 + y ^ 3 + y ^ 2 + 24y ^ 3 + 3y ^ 2 + 3y + 56y ^ 2 + 7y + 7 =

We add similar terms:

8y ^ 4 + 25y ^ 3 + 60y ^ 2 + 10y + 7

WITH ATTACHMENT 1. Find the length of the midsegment. The diagram is not to scale.(1 point)
LUCKY_DIMON [66]
From the given attachment, the triangles are similar.
45/(6x + 4) = 90/(4x + 56)
45(4x + 56) = 90(6x + 4)
180(x + 14) = 180(3x + 2)
3x - x = 14 - 2
2x = 12
x = 12/2 = 6

Length of midsegment = 6x + 4 = 6(6) + 4 = 36 + 4 = 40
