Step-by-step explanation:
do .008 times 5700
Find the standard form of the equation of the parabola with a focus at (-4, 0) and a directrix at x = 4.
Negative multiply negative = Positive
Negative multiply positive = negative
Thus the answer is -4a + 16b - 12c - 12d.
When a number is 3 times a first number. A third number is 100 more than the first number and the sum of the three numbers is 450, the numbers are 70, 170 and 210.
<h3>How to calculate the numbers?</h3>
Let the first number = x
Second number = 3x
Third number = x + 100
Sum = 450
The numbers will be:
x + 3x + x + 100 = 450
5x + 100 = 450
5x = 450 - 100
5x = 350
Divide
x = 350 / 5
x = 70
First number = 70
Second number = 3x = 3 × 70 = 210
Third number = x + 100 = 70 + 100 = 170
Therefore, the numbers are 70, 170 and 210.
