d. 73

Answer 1

The best and the only thing you do here is FOIL it.

Answer 2

hmm...so where are you confused here??

Answer 3

\(\Rightarrow 6(4 + \sqrt7) + \sqrt7(4 + \sqrt7) \)

Answer 4

Do you know distribution?

Answer 5

A

Answer 6

i thought you said FOIL lol =))

Answer 7

\[(a+b)(c+d) = a(c+d) + b(c+d) = ac + ad + bc + bd\]
a = 6
b = sqrt(7)
c = 4
d = sqrt(7)

Answer 8

Well, can you work it out for us?
