Answer: 39$
Step-by-step explanation: 4 hrs and 30 mins and you make 27$
You gotta make the hrs into minutes. So you can find the rate. 4 hrs is 240 minutes. With the 30 minutes its a total of 270 minutes. You're earning 1 dollar every 10 minutes. So i think if i did the math right 390 minutes is 6 hrs and 30 mins. And so she has earned 39$.
Expand the binomial first, then distribute the 4:
4 (<em>x</em> + 1)² = 4 (<em>x</em> ² + 2<em>x</em> + 1)
… = 4•<em>x</em> ² + 4•2<em>x</em> + 4•1
… = 4<em>x</em> ² + 8<em>x</em> + 4
I’m not sure but I think 4 classes have between 27 and 31 students
