What is the value of n? enter your answer in the box. n =

n = 6 is the answer.

Step-by-step explanation:

As we know the theorem if two cords intersect each other within a circle the product of the measures of the segments of one cord will be equal to the measures of the segments of the other cord.

Hence 7 × (n + 4) = 5 × (n + 8)

7n + 28 = 5n + 40

7n - 5n = 40 - 28

2n = 12

n = 6

Therefore n = 6 is the answer.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
