Which amount of 1 inch square pieces of chocolate would you
rather have? Explain the reason for your choice.
a. Enough to cover a rectangle with a length of 9 in. and a perimeter of 22 in.
b. Enough to cover a rectangle with a length of 5 in. and a perimeter of 20 in.

a. Chocolate need to cover a rectangle with a length of 9 in. and a perimeter of 22 inches is 18 pieces of 1 inch square piece chocolates

b.Chocolate need to cover a rectangle with a length of 5 in. and a perimeter of 20 inches is 20 pieces of 1 inch square piece chocolates

Step-by-step explanation

a. To cover a rectangle with a length of 9 in. and a perimeter of 22 in.

perimeter = 2(length+breadth)

Breadth = 22 -9×2  = 22-18 = 4 ÷ 2 = 2 inches

Area of rectangle = 9 × 2 = 18 inches

18 pieces of  1 inch square piece  Chocolate is needed to cover the rectangle

b. To cover a rectangle with a length of 5 in. and a perimeter of     20 in.

perimeter = 2(length+breadth)

Breadth = 20 - 5 ×2  = 10 = 10 ÷ 2 = 5 inches

Area of rectangle = 5 × 5 = 20 inches

20 pieces of  1 inch square piece  Chocolate is needed to cover the rectangle

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 !
