Answer: 0.625
Step-by-step explanation: 5 divided by 8= 0.625
15 servings because 11.25/0.75=15
3/4=.75
11 1/4=11.25
Use the difference of 2 squares (a - b)(a + b) = a^2 - b^2:-
(x - 1/x)(x + 1/x) = x^2 - (1/x)^2
= x^2 - 1/x^2
(x ^2 - 1/x^2)(x^2 + 1 /x^2)
= x^4 - 1/x^4
(x^4 - 1/x^4)(x^4 + 1/x^4)
= x^8 - 1 /x^8 Answer
First you had to remove parenthesis first.
