Since they are consecutive, one is even and the other is odd.
Now, squaring the even number is multiplying it an even number of times, so the answer is even.
Squaring the odd number, however, gives an odd answer.
Substract the first by 1, add it to the second, now they're both even.
Since both numbers are divisible by 2, adding them keeps this ability and thus the answer is even.
Add one to each side, now we have odd + even = odd

Step-by-step explanation:
Blue
;Let the number be x and y
x+y=20
hence:
y=20-x
(x+x^1/2)*(20-x+(20-x)^1/2)=155.55
solving the above we get:
x=6.51285 or x=13.4872
therefore one of the numbers is:
x=6.51285
or
y=13.4872
Answer:
$2 will be your answer
Step-by-step explanation:
If u start with the 85, then add 73 it will add up to $1.58 meaning that since it is above $1.49 you will round up to $2
And both of them indivisually will equal $1 each rounded up
