Geometric mean of
3 and 12: √3 * 12
3 * 12 = 36
√36 = 6
the value of the geometric mean of 3 & 12 is 6
5x8=40 so now we take 16 and subtract 40 we get -24
The answer in exact form is 8/7 and in mixed number is 1 1/7
I believe the answer is 59 .
first , you plug your variables into the equation : 10(3)(2) - (3) + (2) . next , you multiply the 10 and the 3 and the 2 to get : 60-3+2 . now , you add and subtract from left to right to get : 57+2 . now you add those and get 59 .
hope this helps :)
