Answer:

4(2t^2 - 4t - 1)

Step-by-step explanation:

8t²-16t-4​

= 4(2t^2 - 4t - 1)

2t^2 - 4t - 1  is prime so there are no more factors.

Answer:

For me, this quadratic expression can simply be factored by 4 because all the values divide by four. so:

4( {2}t^{2}  - 4t - 1)

Step-by-step explanation:

Just factor it by 4

Answer:

900

Step-by-step explanation:

Each group of 3 starred angles plus the 4th angle which is an interior angle of the triangle has a total measure of 360 degrees. The sum of the measures of the three angles of the triangle is 180 degrees.

total measure of the starred angles = 4 * 360 - 180

total measure = 900 degrees

Ken paid $12 for tow magazines. The cost of each magazine was a multiple of $3. What are the possible prices of the magazines?
Finger [1]
THE MULTIPLE OF 3 ARE: 3 , 6 , 9 ,12
The 1st magazine costs either 3 or 6 or 9 , 12
The 2nd magazine costs <span>3 or 6 or 9 , 12
The value 12 is to be discarded , then are the sum of tall possibilities to get 12:

</span>mag 1st         mag 2nd          total
------------       ------------         --------
3                       9                      12

In triangle xyz, m∠z &gt; m∠x m∠y. which must be true about △xyz? m∠x m∠z &lt; 90° m∠y &gt; 90° ∠x and∠y are complementary m∠x m
Anon25 [30]

m∠X + m∠Y < 90° is true.

<h3>How to solve it?</h3>

XYZ is a triangle.

We have to find the option that is true about △XYZ.

By angle sum property of a triangle,

The sum of all the interior angles of a triangle is always equal to 180°.

So, ∠X + ∠Y + ∠Z = 180°

Given, m∠Z > m∠X + m∠Y.

This implies that ∠Z is greater than the sum of the angles ∠X and ∠Y.

so, ∠X + ∠Y must be less than 90°.

Hence, we can say that ∠X + ∠Y < 90°

Im so confused by this question but my only guess would be that since a coin is a 1/2 chance getting it heads twice is 1/2 * 1/2 which is 1/4 so the person who best they can get 2 heads in a row pays 1/4 of the bet being 5 dollars because 1/4 of 20 is 5 and the person who bets that they can't get two heads pays 15 dollars because that is 3/4 of the bet

tldr: 1/4 chance to get heads pays 1/4 of bet 5$
3/4 chance not to get heads pays 3/4 of bet 15$
