Answer:
D 46x²+ 67x -16
Step-by-step explanation:
adding like terms
R1(x) + R2(x) = 16x²+52x-27 + 30x² + 15x + 11
total = 46x²+ 67x -16
You should write a ( real world situation ) question that can only have whole numbers as a solution because you would divide and then you can not have a fraction left over so instead you add one. For instance there are 132 students going on a field trip. 20 students can fit on each bus. how many buses are needed? 7 because when you divide 132 by 20 you get 6 remainder 12. You can not just make 12 students walk to the location so you would add an extra bus.
Answer:
9
Step-by-step explanation:
Horizontal, by the way don listen to that just trying to get points
9/100 = x/90
Cross multiply to get 810 = 100x
Divide both sides by 100 to get x = 81 inches
