Riley is half as old as Henry. The sum of their ages is 72. How old is henry going tobe nextyear?

1 answer:

3 0

Henry will be 37 next year. If Riley is half as old as Henry then you would divide 72 by 2. That gives you 36 which is how old they both are. Next year Henry will be 37. ( Riley would be too but it doesn't ask for her)

First you need to calculate the value of x when
${x}^{2} + 4x = 45$
the value of x for that is x=-9 or x=5. then on the number line, you will have three different intervals which are:
$x < - 9$
$- 9 < x < 5$
$x > 5$

then you need to choose one number from each of the three intervals to test if you can get
${x}^{2} + 4 < 45$
if you can, then that interval is one of the answer.
so the final answer for this question is
$- 9 < x < 5$
