Answer:
The value of x = 6
Step-by-step explanation:
Points to remember
Solution of a quadratic equation ax² + bx + c = 0
x = [-b ± √(b² - 4ac)]/2a
It is given that,
x² -12x + 36 = 0
<u>To find the solution of given equation</u>
Here a = 1, b = -12 and c = 36
x = [-b ± √(b² - 4ac)]/2a
= [--12 ± √((-12)² - 4*1*36)]/2*1
= [12 ± √(144 - 144)]/2
= 12/2 = 6
The value of x = 6
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: 50
Step-by-step explanation:
Let the number of pizza made last week be represented by y.
From the question, we can form it into:
24% of y = 12
24/100 × y = 12
0.24 × y = 12
0.24y = 12
y = 12/0.24
y = 50
50 pizza were made last week.
Answer: -4x(4x - 15)
Step-by-step explanation:
f(x) = 
+ 60x
y = + 60x
=> - (
- 60x)
=> -4x(4x - 15)
