The automaker of your new car recommends an oil change following the first 5,000 miles and then every 3,000 miles thereafter. If
Jlenok [28]

To determine how many oil changes you will need the first year, you can calculate the number of miles driven the first year and then use that to determine how many groups of 3000 miles you will drive after the first 5000 miles.


1. 52 x 250 = 13000 miles

2. 13000 miles - 5000 miles (1 oil change) = 8000 miles

3. 8000 miles - 3000 miles (1 oil change) - 3000 miles (1 oil change) = 2000 miles


The first year, you will need 3 oil changes.

HELP! PLZ I NEED THIS ASAP
harina [27]

Answer:

2x^{4}+x^{3}-x+2

Step-by-step explanation:

To find which one is prime, let's try to factor them all. We can use the factoring by grouping method.

x^{3}+3x^{2}-2x-6

x^{3}+3x^{2}and-2x-6

x^{2}(x+3)and-2(x+3)

So this one is not prime, since you can still factor it.

x^{3}+2x^{2}-3x-6

x^{3}+2x^{2}and-3x-6

x^{2}(x-2)and3(x-2)

So this one is not prime, since you can still factor it.

4x^{4}+4x^{2}-2x-2

4x^{4}+4x^{2}and-2x-2

4x^{3}(x+1)and-2(x+1)

So this one is not prime, since you can still factor it.

2x^{4}+x^{3}-x+2

2x^{4}+x^{3}and-x+2

x^{3}(2x+1)and -x+2 cannot be further factored.

Therefore, 2x^{4}+x^{3}-x+2 is a prime.

A study samples 100 cat owners and finds that 98 of them really dislike dogs. What inference can be drawn? A) 98% of all pet own
OverLord2011 [107]
Assuming the 100 people sampled are representative of the population as a whole, the answer is choice B. Most people who own a cat would dislike dogs according to the survey. We can only talk about cat owners since the 100 people selected are cat owners. We can't say anything about pet owners in general.

#3 PLEASE!!!! BRAINLIEST ANSWER!!! Solve the equation!! 12(3x+4)-5(2x-6)=6x-22
Vadim26 [7]

12(3x+4)-5(2x-6)=6x-22

36x + 48 - 10x + 30 = 6x - 22

26x + 48 + 30 = 6x - 22

26x + 70 = 6x - 22

20x + 70 = -22

20x = -92

x = -4.6
