The total age of the three children are = 37years
<h3>Calculation of the total age of children</h3>The product of the ages of three children is = 1872.
Let take child 1 = x
child 2 = x
child. 3 = x
Therefore, the age of three children = x³= 1872
Therefore;
X = 12.32448
The age of the middle child = 12.32448 + 12.32448
= 24.64896/2
= 12.32448
Therefore the sum of their ages = 12.32448 + 12.32448 + 12.32448 = 37years.

Answer:
2. A
3. C
4. B
Step-by-step explanation:
2. To answer # 2, just add all the sides together...
(5x-7) + (3x-4) + (2x-6)
= 10x - 17
3. To answer # 3, divide/mulitply both the numerators and denominators by the same number and check to see if that answer matches the displayed answer...
a) 28 divided by 7 is 4, so divide the whole fraction by 7 to see if the fraction is proportional...
28/7 = 4
49/7 = 7
b) 4 goes into 16 4 times so multiply by 4...
4 x 4 = 16
7 x 4 = 28
=
c) 4 goes into 16 4 times so multiply the whole fraction by 4...
4 x 4 = 16
7 x 4 = 28
≠
d) 4 goes into 20 5 times to multiply the whole fraction by 5...
4 x 5 = 20
7 x 5 = 35
C is the answer because the fractions are not proportional.
4) 25% is a quarter of 100%. A third of 100% is 75%.
$120 - 0.25($120) = $90
Another expression for the for sale price is...
B) 0.75($120) = $90
The first (and most typical) way to find distance of two points is by using the distance formula.
One alternative is the Manhattan metric, also called the taxicab metric. This option is much more complicated, and rarely used in high school math. d(x,y)=∑i|xi-yi|
