Ken had the following problem on a quiz: Two sides of a triangle have lengths of 8 feet and 11 feet. If the triangle’s perimeter is 28 feet, what is the length of the third side? Ken solved the problem as shown below. P = a + b + c. 28 = 8 + 11 + c. 28 = 19 + c. 47 = c. Which statement about Ken’s work is true? Ken substituted into the formula incorrectly. Ken added incorrectly when combining like terms. Ken added 19 to both sides of the equation rather than subtracting 19. Ken solved the equation correctly.

step-by-step explanation:

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4

a ≈ 172.05
