Step-by-step explanation:
After putting the values:-
So, there are 1, 5, 10, 25 and 50 cent coins.
The most logical combination would be a dime and a quarter (10 + 25 = 35) but it is said that "one of the coins is not a dime".
But, there is something many people don't notice. It says that one of the coins isn't a dime, but the other one can be a dime. So, the two coins are a quarter and a dime.

Answer:
P = 6x³ + 12x² - 18x + 8
Step-by-step explanation:
Given that:
Length = 3x3+4x2−6x
Width = 2x2−3x+4
The length of fencing needed will be :
Perimeter of rectangle (P) = 2( Length + Width)
P = 2[ (3x3+4x2−6x) + (2x2−3x+4)]
P = 2 (3x³+ (4x² + 2x²) + (-6x - 3x) + 4)
P = 2(3x³ + 6x² - 9x + 4)
P = 6x³ + 12x² - 18x + 8
Answer: Choice D) Opposite sides of a parallelogram are congruent
Likely a typo has been made because A, B, C, and D aren't shown. I think your teacher meant to say PQ = RS and QR = PS
A parallelogram has properties that the opposite sides are parallel, and it can be proven that the opposite sides are congruent as well.
To determine tax, I like to use this method...
1. Make the percent into a decimal
For exmaple, the pretty high tax of 8% would be 0.08, since you need to move the decimal two places to the left regardless.
2. Multiply
For this word problem, multiply 0.08 and 750, or in other words, multiply the original price by the percent/decimal. 0.08×750=60
3. <em>Subtract the tax from the original price if needed</em><em>!</em>
This example only wants the tax, so this step if not needed, but if it were, subtract 60 from 750 to get a total price of $690.
