Step-by-step explanation:
The options include:
A. Jessie earned a total commission of $800 in the first week and x dollars in the second week.
B. Jessie sold 2 cars in the first week and x number of cars in the second week, earning a commission of $400 on each car.
C. Jessie sold 1 car in the first week, earning $800, and x number of cars in the second week, earning a total commission of $1,200.
D. Jessie earned a commission of $800 on each car in the first week and $400 on each car in the second week, selling x number of cars each week.
The situation that could be described by this expression will be option B "Jessie sold 2 cars in the first week and x number of cars in the second week, earning a commission of $400 on each car". This will be:
= (400 × 2) + 400(x)
= 800 + 400x
D/2 + c/3
10/2 + 6/3
5+6/3
=5+2
=7
Answer: 20
Step-by-step explanation:
x+y=5
x-y=4
---------
x+y=5
x=4+y
--------
(4+y)+y=5
4+y+y=5
4+2y=5
2y=1
y=0.5
x=4.5
---------
x²-y²=(4.5)²-(0.5)²=20.25-0.25=20
