Answer: Each piece would be 1/4 or 25%
Step-by-step explanation:
A. X^2-10x. =-8
To complete the square you get half of -10 and then square that number half of -10 is -5 and -5 times -5 equals positive 25 that would you add to each side
x^2-10x+25=-8+25

<span>Equivalent ratios are ratios that name the same comparison. Meanwhile, equivalent fractions </span><span>are fractions that name the same amount or part. Equivalent ratios and equivalent fractions are similar in that the two quantities refer to ratios and fractions that ultimately have the same value but are expressed in a different way. For example, 48/64 is equivalent to 72/96, both have the value of 3/4. </span>
The equation for this should be 4n - 15
Replace x = 3 into <span>6/x + 2x^2
</span>6/x + 2x^2
=6/3 + 2 (3)^2
= 2 + 2(9)
= 2 + 18
= 20
