Answer:
X=13°
Step-by-step explanation:
angle 6 = 69° because they are vertically opposite angles and angle 6 and 5x+4 are equal to each other because they are corresponding angles because given 2 lines are parallel given in question's diagram and then
=> 5x+4 = 69°
=> 5x = 69°-4
=> 5x = 65°
=> x= 65°/5
=> x = 13°

Answer:
8( 3x+2y) ( 9x^2 -6xy +4y^2)
Step-by-step explanation:
216x^3 + 64y^3
Factor out the greatest common factor of 8
8( 27x^3 +8y^3)
Rewriting
8 ( (3x)^3 + (2y)^2))
Recognizing this as the difference of cubes)
a^3 + b^3 = (a+b) (a^2-ab+b^2)
8 ( (3x)^3 + (2y)^2)) = 8( 3x+2y) ( 9x^2 -(3x)(2y) +4y^2)
=8( 3x+2y) ( 9x^2 -6xy +4y^2)
