A taxi charges ₹20 for the first 2 kilometers of travel and ₹x for each subsequent kilometer. If Annie travelled a distance of 25 km, write the expression for the taxi fare paid by her.

total cost = ₹20 + ₹23x

Step-by-step explanation:

She traveled 23 km after the first 2 km.

2 km cost ₹20

23 km cost ₹23x

total cost = ₹20 + ₹23x

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
