Perctange is based on the total number. in this case you don't know it so you cant make such a guess.
2 = 47 degrees
1 = 133 degrees
3 = 133 degrees
2 is opposite of x, so the angles are equal. Angle 2 is 47 degrees
A straight line is 180 degrees. Subtract 47 from 180 to get 133. Therefore, Angle 1 is 133 degrees. Because Angle 3 is opposite of Angle 1, it has the same angle as Angle 1. So Angle 3 is 133 degrees.
Let's start the sum as follows:
x³ = 8
X × X × X = 8
This means there are 3 number which after Multiplication gives answer 8.
If 2 is multtiplied 3 times it will give you 8
Thus the answer of x is 2
x = 2.
Answer:
2x(x+y)(x-y)
Step-by-step explanation:
Given the expression;
(x+y)² + 2(x+ y)(x- y) + (x– y)²
Factorize
(x+y)² + (x+ y)(x- y) + (x+ y)(x- y) + (x– y)²
= (x+y)[x+y+(x-y)] +(x-y)[(x+y)+(x-y)]
= (x+y)(x-y)(x+y+(x-y))
= (x+y)(x-y)(x+y+x-y)
= (x+y)(x-y)(2x)
hence the expanded form is 2x(x+y)(x-y)
