Area = length x width.
24 = (x + 2)(x - 3) = x² - x - 6
x² - x - 30 = 0
(x + 5)(x - 6) = 0
We can eliminate the root x = - 5 because dimensions cannot be negative. So, the only valid answer is x = 6
The length = x + 2 = 6 + 2 = 8 in.
The width = x - 3 = 6 - 3 = 3 in.
2.32*103 = 2.39E3, or 2.39*10^3
This result is likely wrong because I first thought your 103 literally meant 103. Now it seems that you meant 10^3 (10 to the third power). So, ignore the above result and multiply again: 2.32*10^3. This is already in scientific notation.
4.2*10^4 is already in scientific notation.
4.2*10^(-2) is already in scientific notation.
5700=1.7*10^3 (answer in scientific notation)
6548000= 6.55*10^(-6) (in scientific notation)
Yes, because if you devide 2 by 5 it equals a decimal of .4

Answer:
Interest = $6,300 (Approx.)
Step-by-step explanation:
Given:
Amount deposit (P) = $26,000
Number of month = 36 month
Number of year (n) = 36 / 12 = 3 year
Rate of interest (r) = 7.5% = 0.075
Find:
Interest earned
Computation:
Interest = p[(1+r)ⁿ-1]
Interest = 26,000[(1+0.075)³-1]
Interest = 26,000[(1.075)³-1]
Interest = 6,299.71
Interest = $6,300 (Approx.)
