Based on the given parameters, the value of Rx is R18
<h3>How to determine the value of Rx?</h3>
The given parameters are:
Number of people = 25
Amount paid = Rx
Additional people of 5 = Amount paid being R3 less
The total amount paid is calculated using:
Total amount = Number of people * Amount paid
Substitute the known values in the above equation
Total amount = 25 * x
Total amount = (25 + 5) * (x - 3)
Substitute Total amount = (25 + 5) * (x - 3) in Total amount = 25 * x
(25 + 5) * (x - 3) = 25 * x
Evaluate the sum
30 * (x - 3) = 25 * x
Evaluate the products
30x - 90 = 25x
Collect like terms
30x - 25x = 90
Evaluate the like terms
5x = 90
Divide both sides by 5
x = 18
Hence, the value of Rx is R18

Answer: -30b^2+76b+80
Explanation:
Multiply the second parenthesis by each term from the first parenthesis:
3b•2(-2•2+b+10)+4b•(-2b•2+b+10)+8(-2b•2+b+10)
Then distribute 3b•2 through the parenthesis
-24b^2+6b^2+60b+4b•(-2b•2+b+10)+8(-2b•2+b+10)
Then collect like terms
-30b^2+60b+40b-32b+8b+80
Collect like terms=
-30b+76b+80
I THINK THE ANSWER IS B OR C BUT I WOULD GO WITH B HOPE I HELPED
8(51) = 8(50 + 1) = 8(50) + 8(1) = 400 + 8 = 408
