Let g = number of gloves and let h = number of hats. We're going to write a system of equations.
2g+4h=43
2g+2h=30
Now I'm going to isolate a variable in one of the equations. Let's isolate the g in the second equation
g+h=15
g=15-h
Next, I'm going to plug in my new equation for g into the first equation and solve for h.
2(15-h)+4h=43
30-2h+4h=43
30+2h=43
2h=13
h=6.5
Finally, I'm going to plug my solution for h into either equation (I'll use the second one) and solve for g.
2g+2(6.5)=30
2g+13=30
2g=17
g=8.5
If I want to double check my answers, I can plug both values into the first equation and see if I get 43. The hats are $6.50 and the gloves are $8.50.
Depends on what kind of expression you are talking about, A mathematical expression, or a normal expression.

C because if width is 2 and length is 3 area is 6 but if width is 1 ad length is 3 area is 3
Answer:
Expanded Form. When we write the number 521, what that number really means is that we have the total of 500 + 20 + 1. We've expanded the number to show the value of each of its digits. When we expand a number to show the value of each digit, we're writing that number in expanded form.
