Convert all the numbers to real numbers:
6√3 = 10.3923
(3.5)^2 = 12.25
√75 = 8.660
9.8 = 9.8
57/5 = 11.4
A) Now order from largest to smallest:
(3.5)^2, 57/5, 6√3, 9.8, √75
B) We found the order by solving the equations to get real numbers.
C)
Since the numbers are multiplied by a negative number, the greatest number would be the smallest number because it would be closer to zero.
The order would be the reverse of part A:
x√75, 9.8x, 6x√3, 57x/5, x(3.5)^2
D) I replaced x with -1 and calculated for real numbers. All the values were the same as A except they were the negative value.

Answer:
- incorrect
- correct
- incorrect
Step-by-step explanation:
A + B = (-4x^2 +2x -5) +(3x^2 +6) = x^2(-4+3) +x(2) +(-5+6) = -x^2 +2x +1
The given sum is Incorrect.
__
A - C = (-4x^2 +2x -5) -(-5x -4) = -4x^2 +x(2+5) +(-5+4) = -4x^2 +7x -1
The given difference is Correct.
__
B + C = (3x^2 +6) +(-5x -4) = 3x^2 -6x +2
The given sum is Incorrect.
