Remove unnecessary parenthesis, and combine like terms
(3+i) + (5-2i)
3+i + 5-2i
8+i
you added 3+5 which is 5 and i-2i which is "i"
hope this helps.

Answer:
Step-by-step explanation:
In an isosceles triangle, two sides and two angles are equal.
The shortest side of an isosceles triangle is 2x+5 inches. The 2 longest sides are 3 inches longer. This means that the length of each of the longer sides is
2x + 5 + 3 = 2x + 8 inches
The formula for determining the perimeter of a triangle is expressed as
Perimeter = a + b + c
Where a, b and c are the sides of the triangle.
The perimeter of the triangle is 21 inches. Therefore, the equation that can be used to find the length of each side of the triangle is
2x + 5 + 2x + 8 + 2x + 8 = 21
6x + 21 = 21
