Find the perimeter of the following shape and round it to the nearest shape
a. 12
b. 13.9
c. 17.9
d. 20

C

Step-by-step explanation:

The given shape is a square

Calculate the length of AB using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = A(- 3, 5) and (x₂, y₂ ) = B(1, 7)

d =

  =

  =

  =

Perimeter = 4 × = 4 ≈ 17.9

Take a look at line BC. What are the coordinates for each letter?

B = (7, 1) | C = (3, 3)

We are looking for the rise, so look at x (the first number in the parenthesees).

Subtract: 7 - 3 = 4

A square's sides are the same, so now multiply by 4 since there are 4 sides.

4 * 4 = 16 units

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.
