Answer:

\huge\boxed{\sf f(-3) = 18}

Step-by-step explanation:

\sf f(x) = x^2 - 2x + 3

<u>Put x = -3</u>

\sf f(-3) = (-3)^2 -2(-3) + 3\\f(-3) = 9 + 6 + 3\\f(-3) = 18

It takes21 minutes for 5 people to paint 7walls. How many minutes does it take 3people to paint 5 walls?
scoray [572]

so 5 people work each one for 21 minutes, that means 21+21+21+21+21 minutes altogether, namely 105 minutes, it took that long for 7 walls, hmmmm how long for just one wall then? well, 105 ÷ 7, namely 15 minutes then, for just 1 wall.


now, if it takes 15 minutes of work to do one wall, what about 5 walls? well, that'd be 15*5 or 75 minutes.


so if we have 3 folks working, how much would each one work? well, 75 ÷ 3, namely 25 minutes, so each of them will work 25 minutes, namely 25+25+25 minutes, so in 25 minutes, they'll be done with 5 walls.
