You would add the exponents. So you would just add 5 and 2. keep the 3. So it would be 3 to the power of 7
1st). Distribute 7 & 4
2nd). Distribute 7 & 9
3rd). Your equation should look like this " 28 + 63"
Your answer is the 2nd option. ;)
Ok, so equation for this would be 2x-35=9, 2x because its twice a number, x. 35 because it is taking off of 35. 9 because the grand total is 9.
2x-35=9 First add 35 to 9
2x=44 Then divide 44 by 9
x= approximately 4.9
I hope this helps you
