Answer:
B is the answer
x=29 and y=21
Step-by-step explanation:
diagonals of parallelogram bisect each other . so AO will be equal to OC and OB will be equal to OD
Answer:
answer is
x1= 1/2 + 1/2 * i *sqrt(5)
x2= 1/2 - 1/2 * i *sqrt(5)
Step-by-step explanation:
Please refer to the attached picture for the procedure
Keep in mind, that the first step to use the quadratic formula is to rearrange the terms.
The fourth choice goes in the first box.
The second choices goes in the second box.
The fifth choice (the one on the bottom row) goes in the last box.
The fourth choice is 2/6. When reduced it equals 1/3.
The second choice is 3/6. When reduced it equals 1/2.
So when you add them, 2/6 + 3/6, you get 5/6.
Let y and x be the numbers that varies directly (that means they keep the same proportion)
Then we have 7y = 3x, OR y/x =7/3 (this ratio should be kept for any value of x and y:
y/x = 7/3, if y = 28, then 28/x = 7/3 or x = (3)(28)/7 = 12
SO X = 12
