Justify "<span>x2 = 25 is {±5}"
First, please write x^2, not x2.
</span><span>x^2 = 25; solve for x. Take the sqrt of both sides. Must write "plus or minus " in front of the sqrt of 25:
x^2 = 25 becomes x = plus or minus 5, so x: {-5, 5}</span>
To simplify the given equation, you want to combine like terms. Since both terms have x^8, we can add the coefficients and leave the x^8
3x^8-7x^8 (do 3-7)
=-4x^8 so the answer is C
Hope this helps
Percent formula : is/of = %/100
% = n
is = 23
of = 94
now we just sub our numbers into the formula
23/94 = n/100 <===
