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.
Answer:
Will earn $74.38 in interest or for the total $924.38 for the total amount accrued, principal plus interest
Step-by-step explanation:

It says 2 significant figures so the least it can possibly be is 0.5 less and the most it can be is 0.5 more as if it was, lets say 20.4 it would round down to 20 not 21.
<span>X +Y = 13.1 + 2.2
= 15.3

</span><span>D. 15.3</span>
Collect like terms
6.5x-4.5x = 6+10
2x = 6+10
Divide both sides
2x = 16
X= 8
