First, you subtract 2x on both sides

divided on both sides by -3

<span> a • (6ab2 + 2ab - 2a - 3b2 + 4b)
</span>
Step by step solution :<span>Step 1 :
</span><span>Equation at the end of step 1 :</span> (3ab • (2ab + 2a - b)) - 2a • (2ab + a - 2b)
<span>Step 2 :</span><span>Equation at the end of step 2 :</span> 3ab • (2ab + 2a - b) - 2a • (2ab + a - 2b)
<span>Step 3 :</span><span>Step 4 :</span>Pulling out like terms :
<span> 4.1 </span> Pull out like factors :
<span> 6a2b2 + 2a2b - 2a2 - 3ab2 + 4ab</span> =
<span> a • (6ab2 + 2ab - 2a - 3b2 + 4b)</span>
Final result :<span> a • (6ab2 + 2ab - 2a - 3b2 + 4b)</span>
504 because when you multiply 9 by 8 and then by 7 (9x8x7) you get 504.
I believe that it is E since it is pretty obvious where the middle is you just do rise/run which gives you 2,-1
Answer:
The equation can be used to determine the amount of money S(t) that her savings account has after t years is 
Step-by-step explanation:
A student invests $500 in a savings account
Principal = $500
Rate of interest = 4% = 0.04
We are supposed to find equation can be used to determine the amount of money S(t) that her savings account has after t years
Formula : 
Where A is the amount after t years =S(t)
t = time
r = rate of interest in decimals =0.04
P = Principal=500
Substitute the value in the formula :
So, 

Hence The equation can be used to determine the amount of money S(t) that her savings account has after t years is
