A landscaper wants to create a 12-foot-long diagonal path through a rectangular garden. The width of the garden is x feet and th
nasty-shy [4]
If we let x be the width of the garden, then x+4 will be the length. The Pythagorean theorem states that the square of the hypotenuse is equal to the sum of the squares of the legs.

         12² = (x)² + (x + 4)²

Simplifying,

    144 = x² + x² + 8x + 16

Further simplification,

    144 = 2x² + 8x + 16

           x² + 4x - 128 = 0

The value of x from the equation is 6.2 ft. The length is then equal to 10.2 ft.


The answer to this item is the second choice.

Six less than the quotient of a number and two, increased by ten" when n = 8?
Klio2033 [76]

<u><em>Answer:</em></u>

The expression is: \frac{n}{2} + 4

The value at n = 8 is 8

<u><em>Explanation:</em></u>

<u>1- Getting the expression:</u>

Assume that the variable in the expression is n

<u>Now, we check the givens:</u>

The quotient of n and 2 is translated as \frac{n}{2}

6 less than the quotient means that we will subtract from the quotient

<u>Based on the above, the expression becomes:</u>

\frac{n}{2} - 6

Now, the final given states that the expression obtained from above is increased by 10

This means that we will add 10 to the obtained expression

<u>Based on that, the expression we are looking for is:</u>

\frac{n}{2} - 6 + 10 = \frac{n}{2} + 4

<u>2- Getting the value at n = 8:</u>

To get the value of the expression at n = 8, we will simply substitute in the expression we obtained from part 1

<u>This is done as follows:</u>

\frac{n}{2} + 4

\frac{8}{2} + 4 = 4+4 = 8

Hope this helps :)
