The length of the yard is \boxed{22\text{ feet}}.

Further explanation:

It is given that Sally is having a problem with her puppy leaving the yard so she decides to build a new fence.

The length of the yard is 10 feet more than 2 times the width.

She needs 56 feet of fencing to do the job.

Consider the length and width of the yard as x feet and y feet respectively.

And it is given that the length of yard is 10 feet more than 2 times the width.

So, the equation for length is as follows:

\boxed{x=2y+10}         ....(1)

Therefore, the perimeter is calculated as follows:

\begin{aligned}P&=(2\times \text{length})+(2\times \text{breadth})\\&=2x+2y\\&=2(2y+10)+2y\end{aligned}  ...(2)

Also given that she needs 56 feet of fencing to do the job.

Thus, the perimeter of the yard is 56 feet.

Substitute the value of perimeter in equation (2) to obtain the value of y as  follows:

\begin{aligned}2(2y+10)+2y&=56\\4y+20+2y&=56\\6y&=56-20\\6y&=36\\y&=6\end{aligned}

The value of y is 6 feet.

Therefore, the width of the fence is 6 feet.

Now, substitute the value of y in equation (1) to find the value of x as,

\begin{aligned}x&=(2\times 6)+10\\&=12+10\\&=22\end{aligned}

Therefore, the length of the yard is \boxed{22\text{ feet}}.

Let x be the yard length, then if <span>the length of the yard is 10 feet more than 2 times the width, the length of the yard is 2x+10. The perimeter is 2 lengths + 2 widths, so P=2x+2(2x+10) .

Complete the table of values fory=2x^2+x
Semmy [17]

Complete question:

y = 2x² + 2x - 3

x = -2 -1 0 1 2

Answer:

<u>Complete table of values</u>

x:   -2        -1         0          1          2

y:    1          -3       -3          1         9

Step-by-step explanation:

Given;

y = 2x² + 2x - 3

To complete the table of values of the equation above, we substitute the value of x into the given equation and solve for y.

when, x = -2

y = 2(-2)² + 2(-2) - 3

y = 8 - 4 - 3

y = 1

when x = -1

y = 2(-1)² + 2(-1) - 3

y = 2 - 2 - 3

y = -3

when x = 0

y = 2(0)² + 2(0) - 3

y = 0 - 0 - 3

y = -3

when x = 1

y = 2(1)² + 2(1) - 3

y = 2 + 2 - 3

y = 1

when x = 2

y = 2(2)² + 2(2) - 3

y = 8 + 4 - 3

y = 9

<u>Complete table</u>

x:   -2        -1         0          1          2

y:    1          -3       -3          1         9
