4.30 unless it means up a whole number so that would be 5.0
Step-by-step explanation:
-8 and 8 would work :)
This can be solve by cancel of units
Snice red/ bkue = 5/2
And bkue/ green = 3/ 5
So red/ green = (red/ bkue) x( blue/ green)
Red/ green = (5/ 2) x (3/ 5)
Red / green = 3 /2
So the ratio of red is to green is 3: 2

Answer:
2010
Step-by-step explanation:
If the numbers are x and y, you have ...
x +y = 97
x -y = 37
Adding these two equations gives ...
2x = 134
x = 67
y = 67 -37 = 30
The product is then ...
xy = (67)(30) = 2010

<em>Alternate solution</em>
There is no need to find the actual numbers. We can go directly to their product.
(x+y)² = x² +2xy +y² = 97² = 9409
(x-y)² = x² -2xy +y² = 37² = 1369
Subtracting the second equation from the first gives ...
4xy = 9409 -1369 = 8040
xy = 8040/4 = 2010
Of course the difference of squares can be factored, so we could compute ...
(97² -37²)/4 = (97 +37)(97 -37)/4 = 134(60)/4 = 134(15) = 2010
