Answer:
Step-by-step explanation:
Let A should be added in the given polynomial to obtain a sum of zero.
Therefore,
![A + 3 {x}^{2} + 4x + 7= 0 \\ \\ A = 0 - (3 {x}^{2} + 4x + 7 ) \\ \\ A = 0 - 3 {x}^{2} - 4x - 7 \\ \\ A = - 3 {x}^{2} - 4x - 7 \\](https://tex.z-dn.net/?f=A%20%2B%203%20%7Bx%7D%5E%7B2%7D%20%20%2B%204x%20%2B%207%3D%200%20%5C%5C%20%20%5C%5C%20A%20%3D%200%20-%20%283%20%7Bx%7D%5E%7B2%7D%20%20%2B%204x%20%2B%207%20%29%20%5C%5C%20%20%5C%5C%20A%20%3D%200%20-%203%20%7Bx%7D%5E%7B2%7D%20%20%20-%20%204x%20%20-%20%207%20%5C%5C%20%20%5C%5C%20A%20%3D%20%20-%203%20%7Bx%7D%5E%7B2%7D%20%20%20-%20%204x%20%20-%20%207%20%5C%5C%20)
Thus,
should be added in the given polynomial to obtain a sum of zero.
Answer:
Step-by-step explanation:
You need to find the slopes of the line segments.
If the lines are perpendicular to each other, the product of their slopes is -1.
If the lines are parallel, they have the same slope.
Answer:
1 over 2 times 7
Step-by-step explanation:
If you work out all the other problems they equal to 3.5. But 1 over 2 times 7 equals 1/14 so I believe that that is the answer
Your answer is -33!
if you plug it in you get the equation
3+4(5)-8(7)
you’re going to use PEMDAS and first distribute the 5 and 7 so you get the equation
3+20-56
23-56
-33
