If they're integers, that means they can't be fractions (such as 15/2 and 2).
So the only couples of integers that, when multiplied, result in 15 are:
1 and 15
5 and 3.
(there are no other possibilities as both 5 and 3 are not divisible further).
The smaller of the two sums (15+1; 5+3) is 5+3=8.
The least possible sum of a and b is 8.
Look over all of the possible answers. If any of them contains either M or N or both, the result is irrational. There's one exception: N^2 produces a rational number because the radical disappears.
3) 18v2−15v−18
=3(6v2−5v−6)
=3(2v−3)(3v+2)
Answer:
x=4/21
Step-by-step explanation:
2x+4=23x
-2x -2x
4=21x
4/21=x
I think it’s B because 3.14 times 12 is 37.68.
