Answer:
x^2+6x+9
Step-by-step explanation:
expand the expression
$7.64 because 0.68 times 48 is $32.64 and 32.64 - 25.00 is 7.64
The answer is 12.
57 + 39 = 98
98 divided by two is equal to 12.
This can also be shown by multiplication. 12x8=96
I hope this helped you! :)

<h3>How to simplify an expression?</h3>
The expression can be simplified as follows;
4.5 ÷ 0.25 + 2.5 - 0.75 × 8
Hence, using Pemdas rule,
4.5 ÷ 0.25 + 2.5 - 0.75 × 8
18 + 2.5 - 0.75 × 8
18 + 2.5 - 6 = 14.5
Therefore, she made mistake in her step 2 because she was suppose to solve the multiplication before subtraction.
