Answer: (6, -6)
Step-by-step explanation: You didn’t give options or the scale factor, but I believe I’ve seen this problem before. If that’s an option, I believe it should be that one. :)
"Perimeter" is the distance all the way around the drawing. If the drawing has sides, then the perimeter is the SUM of the lengths of all the sides. It's exactly the distance an ant would have to walk along the line, to get all the way around to where he started from.
To get the perimeter of the triangle, you have to add up the lengths of the three sides.
(2a - 3) + (2a) + (3a + 1) =
2a - 3 + 2a + 3a + 1 .
Add up all the 'a's: 2a + 2a + 3a = 7a
Add up all the just plain numbers: -3 + 1 = -2
Write them together, as a binomial: 7a - 2
THAT's your expression for the perimeter.
Answer:
270
Step-by-step explanation:
north to east = 90 degrees
to west = 90 + 90 degrees
90 + 90 + 90 = 270
A composite number is a number that's not prime. A prime number is a number who only has 2 factors (1 and itself). A composite number has multiple factors.
For example;
7 is prime, as the factors of 7 are only 1&7.
14 is composite, as there are 4 factors (more than 2); 1&14, 2&7.
91 is composite, as it has the following factor pairs; 1&91, 7&13.
139 only has 1&19, making it prime.
13 only has 1&13, making it prime.
29 only has 1&13, making it prime.
Your answer is A.) 91.
I hope this helps!
Answer: THe last one.
Step-by-step explanation:
This question is, in essence, basically asking which numbers are less than -3. Looking at the numbers, it is clearly the last set.
