this is
Step-by-step explanation:
number 9 hope it's right
Length of rope bought by Sean = 68 3/4 inches
= 275/4 inches
Then
The number of 15 inch rope that can be made by Sean = (275/4)/15
= 275/(4 * 15)
= 275/60
= 4.58
So we can see from the above deduction that Sean can make 4 complete 15 inches ropes and there will be 0.58 inches of rope excess. <span>I hope
the procedure and the method of solving is absolutely clear to you. This is the

X = -3 - 6i + yi
y = -3i - xi + 6
Answer:
b
Step-by-step explanation:
Distribute parenthesis and collect like terms, noting that the second parenthesis is distributed by - 1
(4x² - 8xy +2y²) - (9x² - 4xy - 7y²)
= 4x² - 8xy + 2y² - 9x² + 4xy + 7y² ← collect like terms
= (4x² - 9x²) + (- 8xy + 4xy) + (2y² + 7y²)
= - 5x² - 4xy + 9y² → b
Given that sequence 1.77, 1.92,2.07 is arithmetic sequence.
Using that we have to find 31st term.
To find that we can use nth term formula of arithmetic sequence which is given by:

where n is the number of term so n=31
t_n indicates nth term
a_1 is the first term so a_1=1.77
r is the common difference which is given by difference of consecutive terms
then r=1.92-1.77=0.15
Now plug these values into above formula





Hence final answer is 6.27.
