6h² + 82h + 120

I'm just going to simplify all of our answer choices, and see which one is correct.

a)  2(3h+ 5)(h + 12)

Simplify.

(6h + 10)(h + 12)

Simplify.

(6h · h) + (6h · 12) + (10 · h) + (10 · 12)

Simplify.

6h² + 72h + 10h + 120

Add like terms.

6h² + 82h + 120

So, A IS CORRECT.

However, let's just go through the rest just to make sure.

b)  (6h + 12)(h - 10)

Simplify. Because we have already showed you the steps on how to multiply this way, I will just simplify it the faster way, without showing all of the work :)

6h² - 60h + 12h - 120

Add like terms.

6h² - 48h - 120

Therefore, B is incorrect.

c)  (6h - 12)(h - 10)

Simplify.

6h² - 60h - 12h + 120

Add like terms.

6h² - 72h + 120

Therefore, C is incorrect as well.

d)  (6h - 60)²

Simplify.

(6h - 60)(6h - 60)

Simplify.

36h² - 360 - 360h + 3600

Add like terms.

-324h + 3240

Therefore, D is also incorrect.

Because A is the only one that is equal to 6h² + 82h + 120, it is correct.

~Hope I helped!~

there are 49 dogs signed up for the dog show. there are 36 more small dogs than large dogs. how many small dogs are signed up fo
pogonyaev
Okay, so total dogs are 49.
So we know if x=large dogs and y=small dogs, then x+y=49.
Next we are told that there are 36 MORE small dogs than large dogs. We can take that more meaning addition, and x being our value for large dogs. So y=x+36.
After that we now know what value we can plug in for y. So x+x+36=49.
We can then simplify it to 2x+36=49.
Subtracting the 36 from both sides, leaves you with 2x=13.
Followed by dividing both sides by 2, gives you x=6.5. Or 6.5 large dogs.
Now we can plug this into our formula for the small dogs (y=x+36) to give us y=6.5+36, which simplifies to y=42.5. Or 42.5 small dogs. Which is our answer.
We can double check it by adding the small and large dogs together, 6.5+42.5, which gives us 49, our total entries.

A study investigated whether price affects people's judgment. Twenty people each tasted six cabernet sauvignon wines and rated h
patriot [66]

Answer:

t=5.5080( to 3 d.p)

Step-by-step explanation:

From the data given,

n =20

Deviation= 34/20= 1.7

Standard deviation (sd)= 1.3803(√Deviation)

Standard Error = sd/√n

= 1.3803/V20 = 0.3086

Test statistic is:

t = deviation /SE

= 1.7/0.3086 = 5.5080

ndf = 20 - 1 = 19

alpha = 0.01

One Tailed - Right Side Test

From Table, critical value of t =2.5395

Since the calculated value of t = 5.5080 is greater than critical value of t = 2.5395, the difference is significant. Reject null hypothesis.

t score = 5.5080

ndf = 19

One Tail - Right side Test

By Technology, p - value = 0.000

Since p - value is less than alpha , reject null hypothesis.

Conclusion:

From the result obtained it can be concluded that ,the data support the claim that the mean rating assigned to the wine when the cost is described as $90 is greater than the mean rating assigned to the wine when the cost is described as $10.
