<span>So you want to factor this polynom thus it will look like something like this
(x+a)(x+b) where a and b can be positive or negative
now in our question the polynom ends with +35 that has no x in it. This part can only come from a*b. Two numbers multiplied can only be positive if they are both positive or if they are both negative.
</span><span>-26x this part comes from ax+bx part of the above equation. If both a and b are poitive than the result needs to be positive as well, this combining the two arguements we come to the conclusion that they are both negative.

Answer:
The equivalent function is
Step-by-step explanation:
Given:
This function represents xth number of the sequence.
We need to re-write the function which is equivalent to given one.
First we distribute the exponent x-1
Hence, The equivalent function is
Answer:
x = 80
y = 15
Step-by-step explanation:
The angle 6y = 90 degrees, because it forms a straight angle with the right angle next to it. 6y and the right angle next to it are also called supplementary angles (added up = 180 degrees)
6y = 90
y =15
x and the angle underneath it are also supplementary angles. We know the angle under x = 100 degrees, because that angle and the one marked 100 degrees are corresponding angles.
x + 100 =180
x = 80
Another way to solve for x is to look at the quadrilateral formed by the lines P and Q with L and M. The interior angles of a quadrilateral add up to 360 degrees. We know 6y = 90 degrees, and the angle above is is also 90, because L&M are parallel and P is perpendicular to them.
360 - 90 - 90 - 100 = 80
