Answer:

x^2 + 11x + 18.

Step-by-step explanation:

The length = x + 9 and the width = x + 2.

So the area

= length * width

= (x + 9)(x + 2)

= x(x + 2) + 9(x + 2)

= x^2 + 2x + 9x + 18

= x^2 + 11x + 18.

Determine any data values that are missing from the table, assuming that the data represent a linear function.

Stells [14]

Answer:

Fill in the blank with 14

Step-by-step explanation:

Given

The attached table

Required

Fill in the gap

Since, the table represents a linear function.

The first step is to calculate the slope of the table

$m = \frac{y_2 - y_1}{x_2 - x_1}$

Where

$(x_1,y_1) = (1,2)$

$(x_2,y_2) = (2,6)$

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{6 - 2}{2 - 1}$

$m = \frac{4}{1}$

$m=4$

The equation of the table is calculated next as:

$y - y_1 = m(x - x_1)$

This becomes

$y - 2 = 4(x - 1)$

$y - 2 = 4x - 4$

Solve for y

$y = 4x - 4+2$

$y = 4x -2$

To fill in the blank;

The value of x is 4

So, substitute 4 for x in $y = 4x -2$

$y = 4 * 4 - 2$

$y = 16 - 2$

$y = 14$

Do you agree? explain why or why not

castortr0y [4]

No. when plugging 4 into the equation, 0 is not the final result. instead it is 6.

square root of 2(4)+1 = square root of 9 = 3

3+3 = 6
and 6 is not 0 so x cannot = 4
