(25 - 20) (divided by) 20 x 100
Is the formula for percentage increase
The answer would be 25%
The two solutions to the given quadratic equation are 2i/3, -2i/3 and they are both complex solutions.
Hence, option C is the correct answer.
<h3>What are the solutions to the quadratic equation?</h3>
Given the equation; 9x² + 4 = 0
First, we subtract 4 from both sides.
9x² + 4 = 0
9x² = -4
x² = -4/9
Take the square roots of both sides
x = ±√(-4/9)
Rewrite -4/9 as (2i/3)²
x = ±√(2i/3)²
x = ±(2i/3)
Hence,
x = 2i/3, -2i/3
Therefore the two solutions to the given quadratic equation are 2i/3, -2i/3 and they are both complex solutions.
Hence, option C is the correct answer.

Answer:
Step-by-step explanation:
Well first you have to find the dimensions of the frame, you can find that by subtracting the dimensions of the photo from the whole dimensions so it will be the
length of the photo and frame - length of the photo = 25- 20 = 5 length of the frame
Now the width of the photo and frame - width of the photo = 20 -16 = 4 the width of the frame
ok so the Area of the rectangle = width x length = 4 x 5 = 20 the Area of the frame
Hope that helps
