Factor the polynomial x2 + 18x + 81 as the product of two binomials
hram777 [196]

Answer:

(x+9)^2

Step-by-step explanation:

We have the polynomial x^2 + 18x + 81 and are being asked to factor this into two binomials.

A rule that I follow is what two numbers multiplied make c (in this case 81) and when added make b (in this case is 18).

So what two numbers when :

A. Multiplied make 81

B. Added make 18

This would be 9.

Now that we have the answer, we can put it into binomials.

(x + 9)(x + 9)

Since these are the same, we can combine it and make it into one.

(x+9)^2

A cat has a litter of 5 kittens. Which simulation could be used to determine the probability that exactly 3 kittens will be fema
kykrilka [37]

Answer:

A. tossing five coins

C. spinning a spinner with 2 equal parts 5 times

Step-by-step explanation:

There are two equally likely outcomes for each kitten's gender: male or female.

A coin has two equally likely outcomes: heads or tails.  So tossing five coins can be used to simulate the probability.

A spinner with two equal parts also has two equally likely outcomes.  So spinning a spinner with two equal parts five times could also be used to simulate the probability.

Over a period of 12 weeks, Carlos ran an average of 21 miles per week. How many kilometers is this? Round your answer to the nea
velikii [3]

Answer:

405.80

Step-by-step explanation:

So, we know Carlos ran 21 miles per week, for 12 weeks....

That makes 21 mi/wk x 12 weeks = 252 miles.

Then we know each km is 0.621 mile.

So, we divide 252 miles by 0.621 mile/km to get= 405.80 km

Dividing miles by miles/km gives us the unit we want (km).

<u>There was a trap in this question,</u> because if instead of dividing the 252 miles by 0.621 you would have multiplied it, you would have gotten another answer listed... just not the right one. :-)
