Answer:
D
Step-by-step explanation:
area of a rectangle is <u>length</u> x <em>width</em>
So, for example for the house you would do <u>30</u><u> </u>x <em>40</em>, which is 1200
Then work out using the same equation for the Backyard and add it to 1200 to find your total area
<span> <span> 20205.97821 is the answer but it is closest to 20,000 so estimated 20,000 would be your answer. </span> </span>
First, write down y=a(x-the x coordinate of the vertex)^2+the y coordinate of the vertex)
second, plug the x coordinate and coordinate of the given point in the above equation to find out a
For example, vertex is (1,2), the point is (3,4)
y=a(x-1)^2+2
then plug in x=3, y=4 in the above equation to find out a
4=a(3-1)^2+2
4=4a+2
4a=2
a=1/2
the equation of the parabola with a vertex at (1,2) and passes through the point (3,4) is 0.5(x-1)^2+2
Answer: classroom numbers are 353 and 355
Step-by-step explanation:
Let x represent the first no
Then x+2 represents the second number
Turn the question to an equation= x - (x +2) =708
Therefore, 2x + 2= 708
2x= 708-2
2x= 706
x= 353 and x+2= 355
