Hey there,
The geometric mean of 4 and 9 is
Reason: The square root of the product of the both numbers.
The geometric mean<span> of </span>4 and 9<span> is 6. </span>4<span> * </span>9<span>. = 6

Combine the terms with j, so -7j+3 would be left.
Answer and Step-by-step explanation:
2x + 2 is the answer.
If the boy is twice as old, and the sister's age is represented by <em>x</em>, then we multiply 2 to x to represent the boy's age.
Then we add 2 when 2 years pass by.

Answer:
3) x = 9
4) x = 3
Step-by-step explanation:
3) The two short segments are indicated as having a sum equal to the long segment.
(x +2) +(-5 +x) = 15
2x = 18 . . . . . . . . . . . . add 3
x = 9 . . . . . . . . . divide by 2
(This makes the segments be 9+2 = 11 and -5+9 = 4, which total 15.)

4) Same deal.
3x +3 = 4x
3 = x . . . . . . . . subtract 3x
(This makes the segments be 3(3) = 9 and 4(3) = 12, where 9+3=12.)
