Answer:
P = 3x +32
Step-by-step explanation:
If we assume the short vertical edge at top center is 10 yards, as it was in two previous problems with this geometry, then we can find the area of the present parking lot as ...
(x-2)(3x) + x(3x -10) +2x(40) = 6x^2 +64x
where the left vertical rectangle is 3x high and x-2 wide; the center area between vertical rectangles is (2x-2)-(x-2) = x wide and (3x-10) high; and the right vertical rectangle is (x-2 +3x)-(2x-2) = 2x wide and 40 high.
As we said, the right vertical rectangle is 2x wide, so the area that has P as one of its dimensions is ...
A = LW = P(2x)
We want this to be the same as the existing area, so ...
2Px = 6x^2 +64x
P = 3x +32 . . . . . divide by 2x

Answer:
9.1 Inches
Step-by-step explanation:
Length of the proposed box=11 Inches
Width of the proposed box=8 Inches
Required Volume,
Volume of a Rectangular Prism =Length X Width X Height
Therefore:
Therefore, the minimum height to the nearest tenth of an inch is 9.1 Inches.
Answer:
A is spanned by vector.
Step-by-step explanation:
The null space of matrix is set of all solutions to matrix. The linearly independent vectors forms subset which are spanned and forms the null space. The null space of vector can be found by reducing its echelon. The non zero rows formed are the null spaces of matrix.
<span>In this case, use variables to represent the numbers, Fortunately, they are all in terms of the smaller number. So. let....
x = small number
(x+3) = middle number
2x = large number
If the sum is 75, then all of the numbers added together must equal this. So......
x + (x+3) + 2x = 75
4x + 3 = 75
4x = 72
x = 18
After we find x, we can conclude that..
Smaller number = 18
Middle number = 21
Large number = 36</span>
