Answer:
w² +9w +20
Step-by-step explanation:
Multiply it out, collect terms, and write as descending powers of w.
(5+w)(w+4) = 5w +5·4 +w² +w·4
= w² +9w +20
Y+4= -4(x-3)
y+4=-4x+12
4x+y=8
This is a combination of 20 studants, 6 to 6:
The range of the data is 93
12x8=96 then 96 divided by 20=4.8, so the answer is 4.8, your welcome! Hopefully you get it right!!☺️
