Answer:
Neither are a solution.
Step-by-step explanation:
The thing is, -4 * -8= 32+5 =37, and you're looking for 29.
3*-8=-24+5=19. If you meant to put positive 8 and not negative, then 3 would be right, but other than that, neither are correct.
You will FOIL this out to simplify. First outers, inners last. 2*1 = 2; 2*2sqrt7 = 4sqrt7; -sqrt7*1=-sqrt7; -sqrt7*2sqrt7 = 2sqrt49. This is what all that looks like:
. Combining like terms we have
. The sqrt 49 is equal to 7, so we can continue simplifying:
which equals
. Finally,
. Or, putting the positive term first, it would also be correct to write
1275 ÷ 9775= 0.1304% or 0.13%
So I think we should multiply 12 by 11/2 and
The answer is 66.
Hope this helps. (:
