Answer:
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.
Answer:
the answer will be W
Step-by-step explanation:
Step-by-step explanation:
-2u = 2i + 10j
V = 4i - 6j
(-2u).V = (2x4) - (10x-6)
= 8 - (-60)
= 68
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.
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. :-)
