Answer: the fourth choice: <span>No, the addition symbol was dropped in the second expression
Justification:
1) The right operation is: </span><span>(4.5m + 7/8) - 9 </span><span>= 4.5m + (7/8 - 9), this is you have to keep the + operator, since you are just grouping the terms in an alternate form.
2) Droping the + operator leads incorrectly to the multiplication of the first term, 4.5m to the terms in parenthesis, instead to the addition, which is what corresponds.
</span>
9; in the two pints there are eight 1/4 pints, and the extra 1/4 makes nine 1/4 pints.

Step-by-step explanation:
Multiplying 0.7 by the original price will work...
If you divide the cost by 100, subtract 30 from 100, you will be left with 70% times the 1/100
70% is also expressed as 0.7, since 7/10=70/100

Answer:
A. (x-5)(x-5)
Step-by-step explanation:
We need to factor x^2-10x+25 into the form (x+y)(x+y) where 2y=-10 and y^2=25
2y=-10
y=-5
So this becomes (x-5)(x-5)
