Answer:

x=7

Step-by-step explanation:

4 *(4+x) = 2 * (2+20)

Distribute

16+4x =2*22

16+4x = 44

Subtract 16 from each side

16+4x-16 = 44-16

4x=28

Divide each side by 4

4x/4 =28/4

Answer:

x =7

Step-by-step explanation:

Secant-Secant Formula:

(whole secant) x (external part) =  (whole secant) x (external part)

4 *(4+x) = 2 * (2+20)

Distribute

16+4x =2*22

16+4x = 44

Subtract 16 from each side

16+4x-16 = 44-16

4x=28

Divide each side by 4

4x/4 =28/4

x=7

I am Lyosha [343]

f(7)≈1.6666                Please mark me as brainliest

round

f(7)=1.67

The domain of the function is the set of all the values of x that would allow the function to have real values. Since the radicand is x - 3, the value of x cannot be less than 3 because that would make the value of sqrt (x - 3) an imaginary number. Thus, the domain should be all numbers GREATER than or equal to 3.
