For the 9 times table, in the answer section, order the answers 9,1,2,3,4,5,6,7,8,9 and then backwards order 0,1,2,3,4,5,6,7,8. This is a very easy way to understand the 9 times table.

One of Marianna's homework problems was to solve the equation below.

Strike441 [17]

Answer:

<h2>Marianna is incorrect because x2</h2><h2>2x13 can be factored into two binomials</h2>

Step-by-step explanation:

ax^2+bx+c = 0

x=−1+√14 or x=−1−√14

discriminant=56

completing square x=−1+√14 or x=−1−√14

Now, we can solve each term for

x=-2 she is incorrect

x(x+2)=0

Now, we can solve each term for

x=0

- no other work needed,

and

x+2=0

x+2-2=0-2

x+0=-2

Using the triangle below, answer the following questions.

fomenos

Step-by-step explanation:

<u>Answer(1):</u>

Law of Cosines.

<u>Answer(2):</u>

since side "c" is missing so we will write formula used for side "c"

$c^2=a^2+b^2-2ab\cdot\cos\left(C\right)$

<u>Answer(3):</u>

First lets write both sine and cosine formulas:

Check the attached picture for the list of formulas:

From given picture we see that two angles A and B are missing. Also 1 side "c" is missing.

Sine formula uses two angles while cosine formula uses only one angles.

Hence cosine formula will be best choice to find the missing values.
