What is the true solution to ln20+ln5=2lnx

A)x=5
B)x=10
C)x=50
D)x=100

B) x = 10

Step-by-step explanation:

ln20 + ln5 = 2lnx

2lnx = ln20 + ln5

Divide both sides by 2:

(2lnx)/2 = (ln20)/2 + (ln5)/2

lnx = (ln20 + ln5)/2

x = 10

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!
