Answer:
option c is the answer for your question
Answer:the correct answer is 2
Step-by-step explanation:
to find the scale factor of similar figures you can divide image over pre-image
so you can divide DF over AC
Step-by-step explanation:
14.2a + 9.8b -13.1b + 0.2a - 3.7a -4.8b
= 14.2a + 0.2a -3.7a + 9.8b -13.1b -4.8b
= .......a + or - ....... b
I don't know any <em><u>slick</u></em> way to do this. I would just list the prime numbers
between 40 and 50 and test them one at a time.
The prime numbers between 40 and 50 are: 41, 43, 47
<u>Test 41:</u>
-- add 1 . . . 42
-- prime factors of 42 . . . 2, 3, 7
-- sum of the factors . . . 12
<u>Test 43:</u>
-- add 1 . . . 44
-- prime factors of 44 . . . 2, 11
-- sum of the factors . . . 13
<u>Test 47:</u>
-- add 1 . . . 48
-- prime factors of 48 . . . 2, 3,
-- sum of the factors . . . 5
Maybe I'm not understanding how to list prime factors, but so far,
I haven't found any number that answers the question.
Maybe if I write the prime factorization of 44 like this:
44 = 2 * 2 * 11
Now the items in the prime factorization do add up to 15.
So the answer would seem to be <em>43.</em>
It's the last one!
Hope this helps!
