Answer:
12
Step-by-step explanation:
Legs of 45-45-90 are equal so 4x-12=x+6.
3x=18, x=6
Plug back in and the length is 12
Answer:
x = ± 
Step-by-step explanation:
Given
5 - 2x² = - 15 ( subtract 5 from both sides )
- 2x² = - 20 ( divide both sides by - 2 )
x² = 10 ( take the square root of both sides )
x = ±
3:2 because 18/12 and 30/20 both reduce to 3/2
