In this case, whose product is 8 and whose sum is 6
2,4
the answer is (n+2)(n+4)
1/8÷1/2
You flip the second one and change it to multiplication:
1/8×2/1=2/8
2/8 can be simplified by dividing both sides by 2:
1/4
Hope this helps :)
29.99-20%= 23.99
25.00-10%= 22.50 so, Mr.chang got the better deal ( but not by much.)
So hmm checking the picture below
you can pretty much just use the pythagorean theorem to get the missing adjacent side
once you have that, you just get the cosine since the cosine is just adjacent/hypotenuse
as far as the sum with θ, those angles would be in your Unit Circle surely
and just expand the sum identity with those values
