Answer:
Explanation:
To find the difference (3c - d)² you should recognize that it is the square of a difference of two terms.
The square of the difference of two terms is a special case that you should remember: it is equal to the square of the first, minus twice the product of the first and second, plus the square of the second:
For the binomial (3c - d)² you have that:
Thus:
- (3c -d)² = (3c)² - 2(3c)(d) + d² = 9c² -6cd + d² ← answer

Answer:
Lexi need to spend <u>6 days</u> to fill the jar with 73 liters of jam.
Step-by-step explanation:
Given:
amount of jam already had in jar =19 liters
amount of jam added each day in jar = 9 liters.
Total number of jam to be needed in jar = 73 liters.
We need to find the number of days required to jar 73 liters.
Solution:
To find the number of days required to jar 73 liters will be equal to amount of jam already had in jar plus amount of jam added each day in jar multiplied by number of days.
framing in equation form we get;
Subtracting both side by 19 we get;
Dividing both side by 9 we get;
Hence Lexi need to spend <u>6 days</u> to fill the jar with 73 liters of jam.
The correct answer is C.
If she needs 45 in of white ribbon for each wreath, then she will need close to 4 feet of ribbon for each wreath. This is because 12 in = 1 foot, and 45 divided by 12 is 3.75.
If she's going to be making 18 wreaths, then she will need 3.75 feet of white ribbon for every wreath:
3.75 x 18 = 67.5.
The answer is -14 ........
