Step-by-step explanation:

G(x) = - x^2 + 10x

a + G(a) = a - a^2 + 10a = - a^2 + 11a or 11a - a^2 or a(11 - a)

1/G(a) = 1/(10a - a^2) = 1/a(10 - a)

x=11 \ \lor \ x=5 \\
\boxed{x=5 \hbox{ or } x=11}

It should be x=11 instead of x=-11, so he is not correct because he made a sign error.

Write any fraction that is less than 1/8
kotegsom [21]
<span>Sample answers are 1/9, 1/10, etc.

Explanation:
To write a fraction less than 1/8, you can keep the numerator 1 and make the denominator any number greater than 8. 1/8 is the same as one part out of 8. Imagine having many pizzas the same size, but cut into different numbers of pieces. 1 piece out of 8 would be a bigger piece than 1 piece out of 9, out of 10, or anything more than 8.</span>
