Answer:
x= 12 units.
Step-by-step explanation:
To solve this equation, we can find each half of the base using the Pythagorean theorem. We will use 'x' as denoting each HALF of the base:
45= 3²+x²
Subtracting from both sides will give us:
36= x²
x=6.
However, the base in this problem is '2x' because 'x' is HALF of the base.
2(6)= 12 units.
Answer:
2x
Step-by-step explanation:
6x^2
-------
3x
6/3 =2
x^2/x =x*x/x =x
6x^2
------- = 2x
3x
