B- 1,350 yd2

C- 2,425 yd2

D- 1,325 yd2

Help

Part 1)  

Part 2)

Step-by-step explanation:

Part 1)

we know that

The perimeter of triangle is equal to the sum of its length sides

so

Part 2)

we know that

The area of triangle is given by the formula

we have

substitute

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
