Kiyo and his friend are designing a rectangular garden with a 2-foot-wide path around it. They want the length of the garden to be 3 times as long as the width. Kiyo and his friend both write quadratic functions to find the area of the garden and path. which one has the correct model? Explain.

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
