Multiply(5+2i)(4-3i) enter your answer in standard form

26-7i

Step-by-step explanation:

1. expand it you will get : 20-15i+8i+6 ( notice that i^2= -1 )

2. simplify it: 26-7i

The correct answer would be choice A).

When the radius of a circle increases, the area does not increase linearly; because the equation for the area is πr², when the radius goes up, the area goes up not by a constant, but by r².

Choices B), C), and D) all describe linear functions; as the side length of a square, the number of gallons of gas purchased, or the time driving increase, the perimeter of the square, the cost of gasoline, and the distance traveled by the car increase at a constant rate.
