Jordan is trying to find the area of the lake in his neighborhood. He sees a duck at Point C and uses a tape measure application on his phone to find the duck is 16 ft from the point of tangency (point B) to the lake, and the point of tangency is 12 ft from the fountain in the center of the Lake (point A).
How far is the duck standing from the fountain?

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

)=3(6x−9)−8

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
