Answer:
13 feet is remaining because
Step-by-step explanation:
12 1/4-3 1/3 (12*4=48+1=49)(3*3=9+1=10)
49/4-10/3
196-40/12
13
Answer:
x = -4 y = -5
Step-by-step explanation:
2x + 3 = -x - 9
3x + 3 = -9
3x = -12
x = -4
y = - (-4) - 9
y = 4 - 9
y = -5
Answer:
Discriminant: 0; 1 real solution
Step-by-step explanation:
To find the discriminant use the formula: b^2 - 4ac.
In this quadratic equation, 9x^2 - 12x + 4 = 0,
Substitute these values into the discriminant equation.
(-12)^2 - 4(9)(4)
Evaluate the exponent and multiply 4 * 9 * 4.
144 - 144
Subtracting these two numbers together gives you 0; the discriminant is 0.
Based on this discriminant you know that there is only 1 real solution to the quadratic equation.
