Determine the factors of x2 − 12x − 20.
FrozenT [24]

Answer:

Step-by-step explanation:

Synthetic division is one way to determine whether or not a given number is a root of the quadratic.  x^2 − 12x − 20 can be rewritten as x^2 - 12x + 36 - 36 - 20, or (x - 6)^2 - 56, which does not have integer solutions:

(x - 6)^2 - 56 = 0 becomes (x - 6)^2 = 56, which works out to x - 6 = ± 2√14.

None of the possible roots suggested in this problem turns out to be an actual root.

correct response: PRIME

The length of one leg of a right triangle is 3 feet more than the other leg. If the hypotenuse is 15 feet find the length of eac
melamori03 [73]

Answer:

Leg1 = 9 and leg2 = 12

Step-by-step explanation:

<u>Points to remember</u>

<u>Pythagorean theorem</u>

Hypotenuse² = Base² + Height²

<u>To find the length of each leg</u>

It is given that, hypotenuse = 15 feet

Let base = x the height = x +3

By using Pythagorean theorem we can write,

Hypotenuse² = Base² + Height²

15²  = x² + (x + 3)²

225 = x²  + x²  + 6x + 9

2x²  + 6x + 216 = 0

x²  + 3x + 108 = 0

By solving we get x = 9 and x -12

Therefore one leg = 9 and other leg = 9 + 3 = 12

The time spent dancing (minutes) and the amount of calories burned can be modeled by the equation c = 5.5t. Which table of value
pishuonlain [190]
To build the table you just have to give values to t and then calculate the corresponding c a per the model.


If the model is c = 5.5 t this is the table

t          c
           5.5 t

0         5.5(0) = 0

1         5.5(1) = 5.5

2          5.5(2) = 11.0

3         5.5(3) = 16.5

4          5.5(4) = 22.0

5          5.5(5) = 27.5


The viables solutions are all where t is equal or greater than 0. You can even use decimal values for t. You cannot use negative values for t.
