Step-by-step explanation:
(2w+−5)(w+7)
(2w)(w)+(2w)(7)+(−5)(w)+(−5)(7)
2w2+14w−5w−35

Answer:
I'm gonna estimate about 240 miles one way
Explanation:
You have a guide on the bottom right-hand corner of the map that tells you how many miles per that amount of distance. As you can see it is split off into tiles incremented by 30. What you do is take a ruler and measure that guide. For example, let's say the map is 9.5cm and the guide is 2cm per 60 miles. The next thing I would do is to measure the distance in centimeters of the physical map between point a and point b which is 8cm. Finally, I convert the centimeters into miles which is (8/2)*60 = 240.
Answer:
It looks like on step c he took away 10 instead of adding 10
Bottom-edgeis 10 cm: 2 ft(30.48cm)
Side-edge is 20 cm : 4 ft(60.96cm)
Poster Area needed = (30.48*60.96)=1858cm2
Paper size = 10*20=200cm2
Need papers= 1858/200=9.3 ~10
.: 10 papers is needed for actual poster.
