Answer:

<h2>B. It is incorrect because the length of the unknown side is the square root of 7,744.</h2>

Step-by-step explanation:

The hypothenuse is 137 units.

One legt is 105.

Using Pythagorean's Theorem, we have

a^{2} =b^{2} +c^{2}\\ (137)^{2}=(105)^{2}+c^{2}\\c=\sqrt{(137)^{2}-(105)^{2}} \\c=\sqrt{18,769-11,025} =\sqrt{7,744}\\ c = 88

Therefore, Gina's process is uncompleted, because the length of the missing leg is the square root of 7,744, which is 88.

So, the right answer is B.

Answer:

The answer is C It is correct because the length of the unknown side is the difference of the lengths of the sides.

Step-by-step explanation:

137^2-105^2=88^2

18,769-11,025=7,744

88*88=7,744

The polynomial p(x)=x^3-7x-6 has a non-factor of (x+1) rewrite p(x) as a product of linear factors.
In-s [12.5K]

Answer:

Using synthetic division suffices to answer your question:

Step-by-step explanation:

Synthetic division is the process by one reduces a large polynomial in your case x^3-7x-6 by a binomial in your case (x+1).

To do so one does the following:

\begin{array}{cccccc}-1|& 1&0&-7&-6\\ & &-1&1&6 \\& 1&-1&-6&0  \end{array}

Since we divided by a linear binomial it reduces the power by one which produces the following quadratic:

(x^2-x-6)

Which can be factored in the following, and I will provide the complete factorization as well:

p(x)=(x+1)(x-3)(x+2)

Question:
Tems11 [23]
A) 1/5 + 5/9

find common denominator:
9*5 = 45

pillow case: 1/5 = 9/45
table cloth: 5/9 = 25/45

9/45 + 25/45 = 34/45 was used 

B. using 45 as the denominator the full piece of cloth would be 45/45
       fraction left over = 45/45 - 34/45 = 11/45 left

C. from A the pillow case uses 9/45, they have 11/45 left, because 9 is less than 11, they have enough to make a pillow case
