A + s = 17
25a + 15s = 305
on solving for the values of two variables. we get a = 5 and s = 12
Answer:
Step-by-step explanation:
<u>Factor x³ + 2x:</u>
1. <u>The common factor is x, then</u>:

Answer:
Her grant in four years time will be of $13108.
Step-by-step explanation:
Exponential equation:
An exponential equation has the following format:

In which A(0) is the initial value and r is the growth rate, as a decimal.
A student get a grant of $10000 a year assuming her grant is increased by 7% each year
This means that 
So



What will her grant be in four years time?
This is A(4). So


Her grant in four years time will be of $13108.
