Answer:

18x^2+19x+35

Step-by-step explanation:

We have been given an expression 5(7-x)+6x(3x+4). We are asked to simplify our given expression.

We will use distributive property a(b+c)=ab+ac to solve our given problem.

5\cdot 7-5\cdot x+6x\cdot 3x+6x\cdot 4

35-5x+18x^2+24x

Combine like terms:

18x^2+24x-5x+35

18x^2+19x+35

Therefore, the simplified form of our given expression is 18x^2+19x+35.

Aleks [24]
Hello there! An equation that can be used to find the total cost of the banquet is this:

225 + 50h + 25p = c

This is because "c" represents the total cost of everything, "h" represents hours, and "p" represents people. The $225 paid to rent a hall is a one-time price and does not go up. $50 is paid per hour to the DJ, and $25 is the amount per person for dinner.

Based on the amount of your monthly bill, if you lived in England, your bill to the nearest hundredth is $185.82

<h3>How to find your bill in pound sterling?</h3>

You have a monthly bill of $304.72. If this was also your bill in England id you stayed there, it would need to be converted to pounds. The way to do this is by using the exchange rate.

If each British Pound is $1.64 U.S. Dollar, then the value of your monthly bill if you lived in England is:

= 304.72 / 1.64

= $185.82
