We can use a ratio expression to find the answer to this problem.

Set up the ratio.
4/5 = x/25
Multiply both sides by 25.
100/5 = x
Divide by 5.
20 = x
This means out of 25 times the ball is kicked toward the goal, the goalie will block it 20 times.

FrozenT [24]

Answer:

√(2 - 7x) + 2x = 0

√(2 - 7x) = - 2x

[√(2 - 7x)]² = (- 2x)²

2 - 7x = 4x²

4x² + 7x - 2 = 0

4x² + 8x - x - 2 = 0

4x(x + 2) - (x + 2) = 0

(4x - 1)(x + 2) = 0

4x - 1 = 0 => 4x = 1 => x₁ = 1/4

x + 2 = 0 => x₂ = - 2
