Answer:
-x^4y + x
Step-by-step explanation:
-2x^7y^2 + 2x^4y + 2x^3y
You can take out 2x^3y because there is enough of that in each part of the equation. Then you just divide the whole numbers and subtract the exponents.
-x^4y + x
In geometry, the angle bisector<span> theorem is concerned with the relative lengths of the two segments that a triangle's side is divided into by a line that bisects the opposite </span>angle<span>. It equates their relative lengths to the relative lengths of the other two sides of the triangle.
so the answer is B</span>
Answer:
1. 3x +7x = 360°
10x = 360
x= 36
measure of first angle = 36*3= 108°
measure of second angle = 36*7 = 252°
Answer:
Step-by-step explanation:
1 will be B, dont know bout 2
It's a summation (sigma) notation.
This expression means the sum of all the terms 
, where <em>i</em> takes the values from 1 to <em>n</em>.
So <em>i</em> is the index (like a counter) and <em>n</em> is the last value.
In this case:
