Answer:x^2 + 9x + 20
Step-by-step explanation:
You could just multiply (x+4)(x+5) and get x^2 + 9x + 20, but judging from the picture, it looks like they want you to split it into 4 rectangles
x^2 +4x+ 5x + 20 =x^2 +9x + 20, just like (x+4)(x+5)
C because you have to think a bout how to get from y to x
Yes -1 is a rational number. We can express it as a fraction of two whole numbers
One way is -1 = -1/1
