Do) 13. Andrea bought a new cell phone. She made an initial payment of $50 to the store, and she will pay $30 each month until the cell phone is paid off. Which
equation represents the relationship between m, the number of monthly
payments Andrea will make, and t, the total amount that Andrea has to pay the
store?
Qui
t = 50m - 30
t = 50m + 30
O
Qo
t = 30m - 50
t = 30m + 50

Asap for seven months an ice creams vendor collects data showing the number of cones sold a day (c) and the degrees above 70 degrees f the vendor finds that there is a positive linear association between c and t that is the best modeled by this equation c=3.7t+98 which statement is true? the model predicts that the average number of cones sold in a day is 3.7 the model predicts that the average number of cones sold i a day is 98 a model predicts that for each additional degree that the high temperature is above 70 degres f the total of number of cones sold increases by 3.7 the model predicts for each additional degree that the high temperature is above 70 degrees f the total number of cones sold increasingly by 98

Simplify. −4x^2 (5x^4−3x^2+x−2) −20x^6−12x^4+8x^3−8x^2 −20x^6+12x^4−4x^3+8x^2 −20x^8+12x^4−4x^2+8x −20x^6+12x^4+4x^3−8x^2

Can someone show me step by step how to do this?
