HURRY Which is the distance between parallel lines with the equations y=-1/3x+3 and y=-1/3x+7
A. 5
B. 3 sqrt(10)
C. sqrt(10) / 7
D. sqrt(3)

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

the answer is c

step-by-step explanation: i took a test with this question on it

f(x) is   are being squared

g(x) is   increasing by 2

h(x) is adding .25 each time

k(x) is taking the square root

f(x) and k(x) are exponential functions
