6x^2 - 18x - 240 = 0
solve for x.
Find solutions that are greatest to least.
The greatest solution will be 8 and least solution will be -5.
A polynomial equation is given which is 6x² - 18x - 240 = 0
We have to find out the solutions that are greatest to least.
What do you mean by the quadratic equation ?
Quadratic equation is a polynomial equation whose highest degree is two . It is expressed in the form of ax² + bx + c = 0.
As per the question ;
Equation is ;
6x² - 18x - 240 = 0
Let's take 6 as common ;
6 ( x² - 3x - 40 ) = 0
or
x² - 3x - 40 = 0
This can be written as ;
x² - 8x + 5x - 40 = 0
x ( x - 8 ) + 5 ( x - 8 ) = 0
or
( x + 5 ) ( x - 8 ) = 0
or
x + 5 = 0
and
x - 8 = 0
So ;
x = - 5 and 8
Thus , the greatest solution will be 8 and least solution will be -5.

Based on your data, what is the experimental probability that the family has two dogs or two cats? (Heads= dogs and tails=cats)
My table:
Heads, Heads
15
Heads, Tails
9
Tails, Heads
16
Tails, Tails
10
Total
50
Also, please explain your answer.
Answer:
Two dogs: 30%
Two cats: 20%
Two dogs OR two cats: 50%
Step-by-step explanation:
Since the total is 50, we have to multiply all the numbers by two. The total will then 100, so one unit in each category will represent one percent. For example, 15 x 2 = 30, so the chance for two dogs is 30%.
If your question meant two dogs OR two cats as a single probability - not the individual probabilities of two dogs and two cat - then it is 50%, because 30 (two dogs) + 20 (two cats) = 50 (two dogs OR cats). I hope this helps! Sorry if my explanation doesn’t make lots of sense, I’m typing this off my phone. Feel free to ask any questions!
Please someone help me!!! ASAP

The water level in a glass decreases 0.4 cm each hour due to evaporation. At the beginning of the experiment, the water level is 12.6 cm.
Let x represent time, in hours, elapsed since the beginning of the experiment and let y represent the water level, in centimeters.
Part A
Construct a linear function, using x and y from above, that determines the water level at a given time, in hours, after the experiment begins.
Part B
How many hours does it take for all of the water to evaporate?
Answer:
Part A
12.6 - 0.4x = y
Part B
x = 31.5
Step-by-step explanation:
Part B
12.6 ÷ 0.4 = 31.5 hours
y=12.6-0.4x is the required linear equation and it takes 31.5 hours to completely evaporate the water in glass.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that in the beginning of the experiment, the water level is 12.6 cm.
The water level in a glass decreases 0.4 cm each hour
Let x represent time, in hours, elapsed since the beginning of the experiment and let y represent the water level, in centimeters.
We need to find the linear function, using x and y from above, that determines the water level at a given time, in hours, after the experiment begins.
y=12.6-0.4x
We need to find how long will it take to for all of the water to evaporate.
12.6/0.4 = 31.5 hours
Hence, y=12.6-0.4x is the required linear function and it takes 31.5 hours to completely evaporate the water in glass.

A barn is shaped like a rectangular prism with a triangular prism on top as shown. The exterior four walls and two triangular faces need to be repainted. If one gallon of paint covers 232 square feet, how many gallons will it take to repaint the barn? Enter your answer in the box.
Answer:
23 Gallons
Step-by-step explanation:
If you do 12 x 38 you get the answer for one half of the triangle if you divide it. However considering it is a whole triangle you dont have to divide it. From there you do 84 x 20 x 2 for the two long rectangular shapes on the barn. Then you do 38 x 20 x 2 for the two shorter ends. Which 38 x 20 x 2 is 1,520 you add 84 x 20 x 20 which is 3360 then you add 12 x 38 which is 456. You add 1,520 + 3,360 which is 4880 then you do 4,880+ 456 which is 5336. From there you would do 5336 / 232 and you would get 23.

Is a triangle with leg lengths of 9 in. and 9 in. and hypotenuse of length √175 in. a right triangle?
Answer:
No
Step-by-step explanation:
a^2 + b^2 = c^2
9^2 + 9^2 = c^2
81 + 81 = c^2
162 = c^2
√162 = c
If it was a right triangle, its hypotenuse would be √162 inches long.

D. 14
Answer:
I know for number 2 its- D. Her probability of winning is an independent event because it depends on the results of her friends’ rolls.
Step-by-step explanation:
ill edit to find the rest of the answers
a) The sample space for Janessa's calculation is [ 5 , 6 ]
b) Her probability of winning is a dependent event because it depends on the results of her friends' rolls.
c) The number of desired outcomes for Janessa's probability is 2.
d) There are 29 possible outcomes
What is Probability?The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
Probability = number of desirable outcomes / total number of possible outcomes
The value of probability lies between 0 and 1
Given data ,
a)
Since Janessa needs to roll a number higher than both her friends to win the game, the possible outcomes for her roll are limited to 5 and 6, since these are the only numbers that are higher than 4 and 3. Therefore, the sample space for Janessa's calculation consists of the numbers 5 and 6, which can be written as [5, 6]
b)
The probability of Janessa winning is a dependent event because it depends on the results of her friends' rolls. If one of her friends had rolled a higher number, then the probability of Janessa winning would be 0. Therefore, the outcome of Janessa winning is dependent on the outcomes of her friends' rolls.
Hence , her probability of winning is a dependent event because it depends on the results of her friends' rolls.
c)
Janessa needs to roll a number higher than both friends, and the only numbers that meet this criteria are 5 and 6. Therefore, the number of desired outcomes for Janessa's probability calculation is 2.
d)
There are a total of 8 + 7 + 14 = 29 pens in the bag. When Denato pulls a pen from the bag, there are 29 possible outcomes since he can choose any of the 29 pens in the bag.
Hence , the probabilities are solved
