y(y+5)

...

4x^2-49 this is a "difference of perfect squares" which always factors to:

(2x-7)(2x+7)

...

5s^2-20 GCF is 5

the taxi charges a flat fee of $3.75, plus $1.50 per kilometer driven. What is the total cost of a 10 km trip?

Lubov Fominskaja [6]

Answer:

$18.75

Step-by-step explanation:

Let

y = Total cost

x = number of kilometers

The equation:

y = 3.75 + 1.50x

If x = 10 km

y = 3.75 + 1.50(10)

= 3.75 + 15

= 18.75

y = $18.75

y = Total cost = $18.75
