Answer:
The equivalent expression is [tex]7(1+i)[/tex]
Step-by-step explanation:
Additional of complex numbers:
When we add complex numbers, we add both it's real parts and imaginary parts.
In this question:
[tex](3 + 2i) + (4 + 5i) = 3 + 4 + (2+5)i = 7 + 7i = 7(1+i)[/tex]
The equivalent expression is [tex]7(1+i)[/tex]
