Area = l x w
trying working it out lmao
(2m + 7) - (3 - 4m) = 2m + 7 - 3 + 4m = (2m + 4m) + (7 - 3)
= <u>6m + 4</u>
So 1 would be 5r+20 and then the second one would be
Let x be the number of people at University B
x + (x+3.5) = 9.5
2x +3.5 = 9.5
2x = 6
x = 3 million students at University B
x + 3.5 = 3 + 3.5 = 6.5 million students at University A
The answer is -403
The order of operations puts multiplication before subtraction. -1 x 372= -372, and -372-31= -403
