Answer:
7/8
Step-by-step explanation:
well first when you put them together like 3/8 and 7/9 you have to simplfy first. You have to cross simplify 3 and 3. Since they are the saem both turn into one. Now you mulitpy. 7 times 1 is 7 and 8 times one is 8. 7/8
Please, post the instructions along with your question, and if possible share the question in symbolic form, not in words.
Do you mean Question #5? By (2) x cube, do you mean 2x^3?
I strongly suggest that you use lots of parentheses ( ) to show how your numbers are grouped, and not to use " x " to denote multiplication (use " * " for that, please.
If only you'll clear this up, I'd be happy to help.
I will assume that your post is 2x^3 - 3(9x-5)^2.
Then 2x^3 - 3(81x - 90x + 25). Does this have any resemblance to what you wanted me to see in your post?
Answer:
x = sqrt (22)
Step-by-step explanation:
This is a RIGHT triangle with the two legs of equal length sqrt 11
us pythagorean theorem
a^2 + b^2 = c ^2 where a and b are the legs and c = hypotenuse
(sqrt11)^2 + (sqrt11)^2 = x^2
11 + 11 = x^2
x = sqrt (22)
