Answer:
x = 1 ; x = -7/2
Step-by-step explanation:

Here the sol. of x =
1) x - 1 = 0
=> x = 1
2) 2x + 7 = 0
=> 2x = -7
=> x = -7/2
Given:
circle inscribed in a square.
Side length of the square = diameter of the circle.
Let x side length and diameter.
Area of a square = x²
Area of a circle = πr²
r = radius ; half of the diameter. = x/2
Area of a circle = π * (x/2)² or π (x²/4)
Ratio of the area of the square to the area of the circle
x² : π(x²/4) or x² / πx²/4
x² * 4/πx² = 4/π
Answer:
- 3 1/4
Step-by-step explanation:
-2 1/2 - x = -5 3/4
(Add 2 1/2 to both sides)
- x = 3 1/4
(Make x positive)
x = - 3 1/4
