given that 4x^2-32x-20+k is a perfect square find k​

Answers

Answer:

k = 20

Step-by-step explanation:

Perfect square identity:

(a + b)² = a² + 2ab + b²

Completing the square:

4x² - 32x - 20 + k = (2x)² - 2*2x*8 + 8² - 20 + k =(2x - 8)² - (20 - k)

In order the given to be a perfect square, we need:

You randomly choose one of the marbles. Without replacing the first marble, you choose a second marble. There are 4 marbles. One yellow, one red, one green, and one blue. Name two ways you can find the total number of possible outcomes.

Answers

The way I see it, there are 16 possible outcomes. I figured this out by there being 4 marbles and 4 different colors. I multiply 4 times 4 and get 16. You could get red and blue, blue and green, etc. It all depends on which color you grab first and which one you grab second. Yes getting green and yellow is technically the same as getting yellow and green but at one point you grabbed green first and the other you grabbed yellow first.

Find the percent of change in the time to run a

mile from June to September. Round to the

nearest tenth of a percent. (Hint, make sure

change each to seconds first!)

7:45

(5:57

June

September

Answers

Answer:

23.225%

Step-by-step explanation:

Runtime in June (x1) = 7:45 = (7 * 60) + 45 = 465

Runtime in September (x2) = 5:57 = (5*60)+57 = 357

Percentage change in Runtime :

[|x2 - x1|÷ x1] * 100%

[|357 - 465| ÷ 357] * 100%

108 / 465 * 100%

0.23225 * 100%

= 23.225%

Answers

Answer:

has no solution.

Step-by-step explanation:

you can see that the two equations are almost identical except for the fact that one is multiplied by 7, but it isnt completely multiplied correctly so there would be no solutions.

Answer:

infinite solutions  

Step-by-step explanation:

you can solve this by the elimination method. take the rover a equation and multiply it by -7 and then combine the equations. when you do this, you can see that either side equals 0 which means that there are infinite solutions.

-7(y= 1.5x - 6) which equals the equation below

-7y= -10.5x-42 then combine the other equation

7y=10.5x+42 and that equals

0=0

Choose the three rectangles that have a perimeter of 12 meters.

Answers

Answer:

I think the answers would be a d and b

Step-by-step explanation:

the perimeter formula for a rectangle is 2L + 2W

if we take the measurements for rectangle a and add 4 + 4, we get 8. then we can do 2 + 2 to get 4. lastly, we would add 8 + 4, which equals 12.

for rectangle d, we can do 3 + 3, which equals 6. because the measurements are the same on each side, we don't have to do another equation and we would just add 6 + 6 to get 12.

and for rectangle b, you can do 1 + 1 = 2 and 5 + 5 = 10, then add 10 and 2 together to get 12.

A situation in which you would need to calculate the surface area or volume of a solid would be when you are going to put up wallpaper in a room. You need to measure the room and the wallpaper.
