Answer:
x = 6
Step-by-step explanation:
Equation: <em>x² - 12x + 36 = 0</em>
Quadratic formula: <em>ax² + bx + c = 0 --> x = (-b ± √(b² - 4ac))/2a</em>
Substitute: <em>x = (12 ± √(12² - 4 * 36))/2</em>
Multiply: x = (12 ± √(144 - 144))/2
Subtract: x = (12 ± 0)/2
Solve: x = 6
Answer:6 1/4
Step-by-step explanation:
4 cans is not enough. he needs 6 and 1/4 cans.
1/10- 2/10- 3/10- 4/10- 5/10
Hope this helps!
He made $2.80 because if you multiply 70 by .04 it’s 2.8
Answer:
44°
Step-by-step explanation:
From sin rule:
a / sin A = b / sin B = c / Sin C
3.6 / sin b = 5.1 / sin 100
Cross multiply :
5.1 * sinb = 3.6 * sin 100
Sin b = 3.5453079 / 5.1
Sin b = 0.6951584
b = sin^-1(0.6951584)
b = 44.039
b = 44°
