Yes but you get a decimal answer
Multiply price per pound by total pounds:
2.50 x 3.5 = 8.75
Total cost = $8.75
The answer
to do the calculus, the method is
taking off the paranthesis
adding the term with a similar degree
summing constant terms
(3x^2+3x+5) + (7x^2-9x+8) =
= 3x^2+3x+5 + 7x^2-9x+8
= 3x^2 + 7x^2 + 3x+5 - 9x+8
= 10x² + 3x - 9x +5 +8
= 10x² - 6x + 13
the answer is
(3x^2+3x+5) + (7x^2-9x+8) =10x² - 6x + 13
the error that Lucia did make 3x - 9x = -12x, instead of 3x - 9x = -6x

Answer:
Both equations have the same solutions.
Step-by-step explanation:
Please consider the complete question:
Determine whether or not the two equations below have the same solution. In two or more complete sentences, explain your rationale.
Let us solve our 1st equation as:
Now, we can see that equation (1) turns out same as equation (2), therefore, both equations will have the same solution.
