The product of the ages 2 years from today is 924
<h3>System of equation</h3>
Let the ages of the three cousins be x, y and z. If the product of their ages is 1716, hence;
xyz = 1716
If the product of their ages last year is 1320, then;
(x-1)(y-1)(z-1) = 1320
Two years ago, the product of their ages will be;
(x-2)(y-2)(z-2) = 1320- (1716-1320)
(x-2)(y-2)(z-2) = 1320-396
(x-2)(y-2)(z-2) =924
Hence the product of the ages 2 years from today is 924

The answer is C,
Coterminal when involving angles is an angle that is 360 degrees greater or lesser. In order to find whether something is coterminal or not you take one of your angles and subtract or add 360 from it until you reach that number. If you add/sub 360 and you can't ever equal the other number than they are not coterminal.
Example:
591 - 360 = 231
So that means
231 degrees = 591 degrees
Example 2:
51 - 360 = 309
51 + 360 = 411
411 + 360 = 771
771, 411, and 309 /= 591 or 231
So 51 degrees /= 231 or 591
C: 51 is not coterminal!

Answer:
The given statement is true.
Step-by-step explanation:
Quadrilaterals are similar if their corresponding sides are proportional.
This statement is true.
Quadrilaterals are similar when
a) corresponding angles are equal
b) the corresponding sides are proportional i,e the ratios of corresponding sides are equal
So, the given statement is true.
Answer: x/3
Step-by-step explanation:
5x²y/15xy
=x²y/3xy ⇔ divide 5 on both sides
=x²/3x ⇔ eliminate y
=x/3 ⇔ divide x on both sides
