A phone company charges $0.45 for the first minute and $0.35 for each additional minute for a long distance call. Which numerical expression can be used to find the cost of a 20-minute phone call? How much does the 20-minute phone call cost?HURRY FIRST ONE GETS BRAINLIEST

$0.45+19*$0.35= $7.1

Step-by-step explanation:

first minute= $0.45

subsequent minutes= $0.35

cost per 20 min= $0.45+19*$0.35= $7.1

cost per x min= 0.45+(x-1)*0.35= 0.35x +0.10

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
