Answer:
<em><u>942.84 cm³</u></em>
Step-by-step explanation:
volume of 1 can = πr²h = 22/7 × 5/2 × 5/2 × 8
= 157.14 cm³
volume of juice in 6 cans = 6 × 157.14 = 942.84cm³
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
