Arectangular garden of area 48 square feet is to be surrounded on three sides by a brick wall costing 20 dollars per foot, and on the fourth side by a fence costing 10 dollars per foot. find the smallest amount of money that can be spent on materials.

$484.97.

Step-by-step explanation:

For a minimum amount of wall/fencing the garden has to be a square.

That would make each side of the garden = √48 dollars.

So the smallest amount  would be √48 * 3 * 20 +√48 * 10

= $484.97.

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
