SA = 2(5)(9)+5²
SA = 90+25
SA = 115
Answer:
5x − 4 = 3x + 8
5x - 4 <em>+ 4</em> = 3x + 8 <em>+ 4</em>
5x = 3x + 12
5x <em>- 3x</em> = 3x + 12 <em>- 3x</em>
2x = 12
2x <em>/ 2</em> = 12 <em>/ 2</em>
x = 6
The greatest common factor is 48

Answer:
17640
Step-by-step explanation:
at a discount of 10% per year $4900 is equal to $490 per year
payment started 6 years ago from now and ended 20 years from now
therefore there is an accumulation of 26 years
for 26 years = 26 *$490= $12740
present value therefore = $4900+$12740=$ 17640
