The three angles are 36 , 72 and 72.
Answer:
$180.00
Step-by-step explanation:
300 * .40 = 120
300 - 120 = 180.00
Answer:
e(x) = d(x)+4
Step-by-step explanation:
d(x) = ( x +2)^2 -4
Add 4 to each side
d(x) +4 = ( x +2)^2 -4+4
d(x) +4 = ( x +2)^2
We know that (x=2)^2 = e(x)
d(x) +4 = e(x)
e(x) = d(x)+4
The answer to the question, <u>What is true about the graph of the parabola described by the quadratic equation</u> is that the parabola crosses the x-axis at x = ±16.
Since the quadratic equation has roots x = ±16, it implies that its factors are x - 16 and x + 16.
So, the quadratic equation is y = (x - 16)(x + 16) = x² - 16²
Also, we know that the roots of a quadratic equation are the points where the value of the quadratic equation equals zero. At this value, the quadratic equations crosses the x-axis at the roots of the quadratic equation.
Since the roots of our quadratic equation are x = ±16, it implies that the parabola crosses the x-axis at x = ±16.
So, the answer to the question, <u>What is true about the graph of the parabola described by the quadratic equation</u> is that the parabola crosses the x-axis at x = ±16.
