I’m pretty sure it is 66 since the base would be congruent to the top so plug in 7 into 10u-4 and u get 66!! (You plug in 7 since u=7)
Jean and Jonathans' age illustrate arithmetic sum, and the sum of their ages in three years time is x + y + 6
<h3>How to determine the sum of their ages?</h3>
Currently, their ages are:
Jean = x
Jonathan = y
In 3 years, their ages would be:
Jean = x + 3
Jonathan = y + 3
So, the sum of their ages is:
Sum = x + 3 + y + 3
Evaluate
Sum = x + y + 6
Hence, the sum of their ages in three years time is x + y + 6
