With showing work can anybody : ( ? ?

Step-by-step explanation:

4 and a half is 4.5 and 3/4 is 0.75

so to get the answer we divide the larger number by the smaller one to get the answer.

3/4 goes into 4 1/2, 6 times

Hope this helps ☺

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
