Will give 60 points if completed. Please help me!
Lerok [7]

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.

Step-by-step explanation:

Hey there!!

During evaluating the expression, you must follow,

  • put the value as given.
  • work according to the mathematical operation sign.

Here,

i). \: b +  {c}^{2}

= 30 +  {6}^{2}

= 30+36

= 66.

ii). b-4c

= 30 - 4×6

= 30 - 24

= 6
