(-55 +94i) + (13 – 12i) =

Express your answer in the form (a + bi).

(−55+94i) + (13−12i) = (−42+82i)

Step-by-step explanation:

The sum of the two complex numbers, (a+bi) and (c+di), is ((a+c) + (b+d)i)

( -  55 +  94i) + ( 13 -  12i) =

 ( -  42 +  82i)  

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
