Answer:
Volume: 3x2x4=24 so the volume is 24 Meter3
Surface area:
52 Square meter
For this case we propose a system of equations:
x: Let the variable representing the quantity of Granny Smith apples
y: Let the variable representing the number of Gala apples
According to the statement we have:

From the first equation we have to:

replacing in the second equation:

So, Carl bought 7 Gala apples
On the other hand:

So, Carl bought 12 Granny Smith apples
Answer:
Carl bought 7 Gala apples and 12 Granny Smith apples
I can’t see it needs better lighting
Answer:
The answer is - x² - 12x + 9
Step-by-step explanation:
1. Using (a-b)²= a²-2ab+b², expand the expression
2. Collect the like terms.
