This is an excellent practice for the solution of quadratic equations.
1*36=36 => (1,36)
2*18=36 => (2,18)
3*12=36 => (3,12)
4*9=36 => (4,9)
6*6=36 => (6,6)
9*4=36 => (9,4)
12*3=36 => (12,3)
18*2=36 => (18,2)
36*1=36 => (36,1)
We can see that the sum decreases until the two factors are close (or equal) and then increases again.
The pair of integers with a sum of 20 is therefore (2,18) or (18,2).
Answer:
9
Step-by-step explanation:
In order to round to the nearest ten you must think: what is the nearest multiple of 10. For example, to round 68 to the nearest 10, the nearest whole number is 70, so the answer would be 70. However if you were to round 63 to the nearest 10, to would be 50 since that is the nearest multiple of 10
Answer:
The answer it's the c
Step-by-step explanation:
1 Trillion it's 1.000.000.000.000
4 * 10^13 it's 40.000.000.000.000
2 * 10^7 it's 20.000.000
2 * 10^7 * 2 * 10^7 it's 4 * 10^14
The answer is 30 hope this helps
