Answer:
8x² + 8
Step-by-step explanation:
Given
(x² + 3)² - (x² - 1)² ← expand both factors using FOIL
= 
+ 6x² + 9 - ( - 2x² + 1) ← distribute by - 1
= + 6x² + 9 - + 2x² - 1 ← collect like terms
= 8x² + 8
Answer:
y = 5/2x - 5
Step-by-step explanation:
You have to rearrange the equation so that it is equal to y.
5x - 2y = 10
(5x - 2y) - 5x = -5x + 10
-2y = -5x + 10
(-2y)/-2 = (-5x)/-2 + (10)/-2
y = 5/2x - 5
What do you mean by that i mean yeah you can have as many as needed to subtract
The correct answer is: AB
Explanation:
There are two ways you can understand this:
1. By drawing:
A ------ C ------B
As you can see the point C is between A and point B, hence AC + CB = AB. One thing to remember here is that point C can be anywhere between the point A and B, in that case, the answer will remain be the same AB. For instance:
A --- C -------------B
Again, AC + CB = AB.
2. By inference:
If the point C is between points A and B, it means that the point C lies on the line AB; if point C were not on the line AB, it will not be between points A and B. Hence, you can infer that AB is a line and point C lies on it and is between points A and B.
The third term was likely to be 25. You can see a pattern -6 when it goes up a term.
