Answer:

1/12

Step-by-step explanation:

the quarter has 2 sides and the cube has 6 your looking tails and a 5 the best way to put this is h1 h2 h3 h4 h5 h6 as that stands for heads and 1-6 then we can say that tails will have the same thing t1 t2 t3 t4 t5 t6 and we're looking for t5 and that only shows up once out of the 12 options

One root of the quadratic equation x^2 − 2x + m = 0 is 9. If the other root is n, what is n−m?

mote1985 [20]

$9^2-2*9+m=0\\
\\
81-18+m=0\\
\\
m=-63$

$x^{2} -2x-63=0\\
\\
\Delta=(-2)^2-4.1.(-63)=4+252=256\\
\\
x=\frac{2 \pm 16}{2}\\
\\
x_1=\frac{18}{2}=9\\
\\
n=x_2=\frac{-14}{2}=-7\\
\\
n-n=-7-(-63)=-7+63=56$

Use the associative property<br> write an equivalent expression.<br> (5 + 7) + x =

Firdavs [7]

<h3>Answer:</h3>

5+(7+x)

<h3>Step-by-step explanation:</h3>

Finding an Equivalent Expression

The associative property of addition states that you can move the terms that are inside the parentheses and still have the expression remain true. So, in the answer above, I moved 5 out of the parentheses and x into the parentheses. No matter the value of x the value of the expression will remain the same

Examples and Proof

Another example of the associative property could be (1+6)+3 = 1+(6+3). To prove this statement we can evaluate each side of the expression.

First, let's do (1+6)+3

(1+6)+3
(7)+3
10

Next, let's do 1+(6+3)

1+(6+3)
1+(9)
10

As you can see both of these expressions are the same, thus proving that the associative property works in this situation.

The measure of a side of a square is x units. A new square is formed with each side 6 units longer than the original squares sid

aliya0001 [1]

To answer this, you will represent the new side length of the square as x + 6.

To find the area you will multiply (x + 6) by (x + 6).

To do this, you will multiply x and x, x by 6 twice and 6 by 6.

See the attached picture for the expression representing the area of the new square.
