If you mean <span>2x3(5x3 − 7)
2x3(15-7)

48
if you mean 2x^3(5x^3-7)
</span>2x^3(5x^3) - 2x^3(7)

Regular price : $44
Discount : 25%
So, discount amount : 25% of 44
= 25/100 × 44
= $11
So, amount after applying discount = $44 - $11 = $33
<span>Payment. While payment is the sum of money paid in exchange for something either goods and services; the money can be credited (or added) into an account directly without making direct payment. We can also credit our account which is also payments. The most efficient way of building a savings is having a set minimum or percentage for saving whichever is greater. Sometimes we may need to save more than our "set minimum" especially when we earn more. The higher we earn the more our set minimum pales in comparison to what we ought to save. On the other hand if we have a set percentage it would also need to be raised higher when we earn more, but saving whichever is greater ensures that we make the best and most efficient savings decision at any period in time.</span>
<span>Suppose 2x + y = 15 -----eq 1
. x + 3y = 20 -----eq 2.
Multiplying eq (1) by 1 and (2) by 2 and subtracting the result
We have: 2x + y = 15 and 2x +6y =40.If we subtract, we have y - 6y = 15 - 40.
So we have -5y = -25. y is 5. Substiting into eq (1), we have 2x + 5 = 15. 2x = 15-5 =10 Hence X =5.Hence option B is the correct option.</span>
