Answer:

Answer:

The width is 4 units, and the length is 10 units.

Step-by-step.

Step-by-step explanation:

area of rectangle = length * width

Let L = length; let W = width.

"The length is 6 units greater than the width.": L = W + 6

area = LW = 40

Since L = W + 6, we substitute L with W + 6.

(W + 6)W = 40

W^2 + 6W = 40

W^2 + 6W - 40 = 0

(W - 4)(W + 10) = 0

W - 4 = 0 or W + 10 = 0

W = 4 or W = -10

A width cannot be a negative number, so we discard the solution W = -10.

W = 4

L = W + 6 = 4 + 6 = 10

The width is 4 units, and the length is 10 units.

Solve this system of linear equations. Separate the x- and y-values with a comma.
vodomira [7]

Answer:

x = \frac{5}{2}, y = \frac{5}{4}

Step-by-step explanation:

1. Isolate for x in one of the equations:

2x = 9x - 14y

2x-9x = 9x-9x -14y

-7x = -14y

-7x/-7 = -14y/-7

x = 2y

2. Substitute 2y in for x in the second equation:

9(2y) = 40 - 14y

3. Simplify:

18y = 40 - 14y

4. Isolate for y:

18y+14y = 40 -14y+14y

32y = 40

32y/32 = 40/32

y = \frac{5}{4}

5. Substitute the new y-value into the simplified expression x = 2y:

x = 2(5/4)

x = \frac{5}{2}

hope this helps!

Which expression is a perfect cube?<br> A. x8<br> B. y24<br> C. m28<br> D. x64
OLEGan [10]

Answer:

B. Y²⁴

Step-by-step explanation:

For perfect cubes, the exponents are a multiple of three. If yᵃ is a perfect cube, then a/3=k where k is a whole number.

Among the provided choices, the exponent of y²⁴ is divisible by 3.

24/3 = 8.

Thus y²⁴ is a perfect cube.

This bar graph shows the number of hurricane in the Atlantic Basin from 2006-2011. Find the amount of change and the percent of
Arada [10]

Answer:

Step-by-step explanation:

Number of hurricanes in year 2008 = 8

Number of hurricanes in year 2009 = 3

Decrease in number of hurricanes = 8 - 3 = 5

Percent of decrease in number of hurricanes = \frac{5}{8}\times 100 = 62.5%

Number of hurricanes in year 2010 = 12

Number of hurricanes in year 2011 = 7

Decrease in number of hurricanes = 12 - 7 = 5

Percentage decrease in number of hurricanes = \frac{5}{12}\times 100 = 41.7%

Decrease in numbers of hurricanes in year 2010 - 11 was same as in year 2010 - 11.

Percentage decrease in hurricanes were more in year 2008 - 09 than percentage decrease in year 2010 - 11.
