Rhea is solving a math puzzle. to find the solution of the puzzle, she must find the product of two numbers. the first number is the sum of 23 and x, and the second number is 18 less than two times the first number. which of the following functions represents the product of these two numbers?

Function which represents the product of these two numbers is:

(23+x)(28+2x)

Step-by-step explanation:

The first number is the sum of 23 and x

i.e. First number=23+x

The second number is 18 less than two times the first number.

i.e. Second number=2(23+x)-18

                                = 46+2x-18

                                = 28+2x

Product of the two numbers=(23+x)(28+2x)

Hence, function which represents the product of these two numbers is:

(23+x)(28+2x)

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
