Answer: Total cost to make 12 pennants is $52.5.

Step-by-step explanation:

Since we have given that

There is a rectangle and a triangle.

Length of rectangle = 1 ft

Width of rectangle = 3 ft

So, Area of rectangle is given by

Area=Length\times Breadth \\\\Area=1\times 3\\\\Area=3\ ft^2

Base of triangle = 1 ft

Height of triangle = 1 ft

So, Area of triangle is given by

Area=\frac{1}{2}\times base\times height\\\\Area=\frac{1}{2}\times 1\times 1\\\\Area=\frac{1}{2}\ ft^2

So, Total area of the pennants will be

3+\frac{1}{2}\\\\=\frac{6+1}{2}\\\\=\frac{7}{2}\ ft^2

Number of pennants = 12

Cost per square foot of pennant = $1.25

So, Total cost for 12 pennants is given by

12\times \frac{7}{2}\times 1.25\\\\=\$52.5

Hence, Total cost to make 12 pennants is $52.5.

Tricia completed the square of the quadratic function f(x)=x^2+14x+2 and determined the coordinates of the minimum value are (-7
eduard
To complete the square you halve the coefficient of the x term and square it. Half of 14 is 7 and 7² is 49. So we add 49 and subtract 49, which means we are not changing the value of the quadratic. So we have x²+14x+49-49+2. This can be written: (x²+14x+49)-49+2, which is (x+7)²-47, which is answer a.
