Surface area of a cube = 6a²
where a = the length of a side.
6(2/3)² = 6(4/9) = 24/9 = 8/3 units² or 2 2/3 units²
Step-by-step explanation:
If a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally.
Because there is no equal sign, we can't know or find what x =. We can only simplify by adding like terms.
3x + 2x = 5x
-6 + 9 = 3
5x + 3 is the simplified answer.
X^2-6x-27 = (x-9)(x+3), therefore (a) is the correct answer
