Since they are consecutive, one is even and the other is odd.
Now, squaring the even number is multiplying it an even number of times, so the answer is even.
Squaring the odd number, however, gives an odd answer.
Substract the first by 1, add it to the second, now they're both even.
Since both numbers are divisible by 2, adding them keeps this ability and thus the answer is even.
Add one to each side, now we have odd + even = odd
1 yard = 3 feet = 36 in
so 1 in = 1/36 yard, 1 ft = 1/3 yard.
The volume of the layer of the topsoil, is:
5 in * 23 ft * 17 ft = 5 *(1/36)*23*(1/3)*17*(1/3) yard cubed =
(5*23*17)/(36*3*3)= 1955/324=6.034 yard cubed.
The store only sells increments of 1/4 = 0.25 cubic yards.
we need 6.034/0.25=24.136
So we need to buy 25 (24 will not be enough) increments of 1/4 cubic yards.
Answer: 25 increments of 1/4 cubic yard, that is 25*0.25=6.25 cubic yards.

Answer:
D. (-2,1)
Step-by-step explanation:
we have
This is the equation of a vertical parabola open upward The vertex represent a maximum
Convert the quadratic equation in vertex form
where
(h,k) is the vertex
Complete the square
Rewrite as perfect squares
The vertex is the point (-2,1)
Step-by-step explanation:
y1/x1=y2/x2
2/5÷1/3=y÷1/4
y=3/10=0.3
