You got the equation correct
Answer:
X = 1 , -2
Step-by-step explanation:
Given in question as,
(log4(x² + x))² = 0.25
log4(x² + x) = 0.5
Applying log base property if log(a)X = b, then X =a^b
Or, x² + x = 4^0.5
x² + x = 2
x² + x - 2 = 0
x²+2x-x-2 = 0
(x + 2) (x - 1) = 0
So, x = 1 and -2 Answer

Answer:
2√(225 -x²)
Step-by-step explanation:
Let 2y be the length of the second diagonal. The half-diagonals and the side of the rhombus form a right triangle. The Pythagorean theorem tells us the relationship between sides and hypotenuse is ...
x² +y² = 15²
y² = 225 -x²
2y = 2√(225 -x²2) . . . . the length of the second diagonal
