A rectangular swimming pool is 50 meters long and 25 meters wide. A concrete walkway with a width of x meters will surround the pool. The combined area of the pool and the walkway will be 1736 square meters. Solve the equation (50+2x)(25+2x)=1736 to find the width of the walkway. Justify that your answer is reasonable.

problem:

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

f(5/2) = 10/3

i hope this !
