Hey there!!
Okay so here are the steps....
(5 + 2i) + (8 - 3i) <---- when we have exponents we should worry about the "i" because it is equal to √-1 but here it isn't the case.
<u>
(13 - i)</u><u /> <----- This is the answer!
<u />I hope this helps! ^__^
The answer is,

Also equivalent to about, 0.185188.
Answer: Option C
Step-by-step explanation:
Given the quadratic equation
, substitute
:

In this case, to find the solutions of the given quadratic equation, you must factor out the variable "x". Then:

Therefore, you get that the solutions of this equation are the following:

Then, the answer is:
This matches with the option C.
What should we find...
Probably base and the height...
Area = 1440cm²
base = 5×height
base = 5h
Area of triangle = base × height
1440 = 1/2 × 5h × h
1440 = 5h²/2
5h² = 2880
h² = 2880/5
h² = 576
h=24cm..
Height = 24cm
Since base = 5h
Base = 5×24
Base = 120cm...
Hope this helped....
Base =
I think it’s what ever you have left after paying, I’m sorry if this is wrong.
