(-2 = √x - 7)x² (calculate)
(-9 = √x)x² (remove the parantheses)
-9x² + √x x²

and you can expand the numerator if you wish, it won't be simplified further though.
I only know how much does the fruit costs per pound is $4.82
5x2=10
5+2= 7
Answer: 5 and 2
S=2LW+2LH+2WH
First, subtract 2LH from both sides
S-2LH=2LW+2LH-2LH+2WH
S-2LH=2LW+2WH
Separate out the W
S-2LH=W(2L+2H)
Divide by 2L+2H to get W alone

Hope this helps.
