7x(√x - 7√7) Multiply √7x to "√x" and "-7√7" respectively:
√7x*√x - 7√7*√7x
First is to simplify: √7x² - 7√7²x
Extract the squares: x√7 - 7*7√x
Then, we simplify: x√7 - 49√x
After simplifying the equation, I got the answer x√7 - 49√x.
-13 (q + 4) = 7q + 16
I think to solve it you do this first:
-13q + -52 = 7q + 16
And then I think you do:
-6q + -36
And thats all I can remember sorry ):
Or
That -6q + -36 might be the answer I think (:
Hope I could help (:
