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

3(4)^0, 3(4)^1, 3(4)^2 ... =

Step-by-step explanation:
x+3/x-2 - 1-x/x= 17/4
now let's put the expression on the upper side so it I'll be
x+3-x-2-1-x-x= 17×14
x-x-x-x+3-2-1= 238
+3-3= 238
= 238 answer
Answer:
The correct option is B.
Step-by-step explanation:
The given equation is
This equation represent the number of open blossoms in a nursery after x hours.
At initial the number hours is 0.
