1. A soccer field has an area (A = LW) that is represented by the polynomial 1 point

matrenka [14]

Answer:

$(x + 6)(x - 6)$

Step-by-step explanation:

Given

See attachment for soccer field

Required

The possible dimension of the field

From the attachment, we have:

$Area = x^2 - 36$

$Length = x +a$

$Width = x + b$

So, we have:

$Length * Width = Area$

This gives:

$(x + a)(x + b) = x^2 - 36$

Express 36 as 6^2

$(x + a)(x + b) = x^2 - 6^2$

Express as difference of two squares

$(x + a)(x + b) = (x + 6)(x - 6)$

Hence, the dimension is: $(x + 6)(x - 6)$

What is the slope of the line that contains the points (7, -3) and (-7, 4)?

tino4ka555 [31]

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

$m = \dfrac{-3 - 4}{7 - (-7)}$

$m = \dfrac{-7}{14}$

$m = -\dfrac{1}{2}$

Answer: The slope is -1/2.
