A long-distance telephone company charges a rate of 6 cents per minute or a 40-cent minimum charge per completed call, whichever is greater. find the cost, in cents per minute, for a 3-minute call.

charges per call are the maximum of $0.40 or $0.06 per minute

the charge for a 3-minute call

maximum( $0.40, $0.06 × 3 ) = maximum( $0.40, $0.18 ) = $0.40

The charge for a 3-minute call is $0.40.

d.192

step-by-step explanation:

12*16=192

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
