Answer:
5x^2 +10x
Step-by-step explanation:
The area is the product of the height and width. For this exercise, it is convenient to compute the rectangle areas individually, then write their sum:
blue rectangle area = (5x)(x) = 5x^2
red rectangle area = (5x)(2) = 10x
Total area = 5x^2 +10x.
_____
If you start by writing an expression for the total area, expanding it requires you deal with the unlike terms separately anyway:
5x(x +2) = 5x(x) +5x(2) = 5x^2 +10x
Assuming you want to solve for x the result can vary. The result can be shown in multiple forms. Hope this helps!

Answer:
Graph A
Step-by-step explanation:
The graph of a proportional relationship is a straight line through the origin. Only graph A goes through the origin.
Rick started with 10/10 of the grapes because he had all of them at the start.
Then he gave 2/10 and 4/10 of the grapes away.
10/10 - 2/10 - 4/10 = 4/10 = 2/5 left
answer: Rick had 2/5 of the grapes left.
