Answer:

Step-by-step explanation:

Hint:

a² - 9a + 15 = (a-7)(a-2)

a² + 9a + 15 = (a+7)(a+2)

a² + 3a - 10 = (a-2)(a+5)

a² + 5a - 14 = (a-2)(a+7)

a² - 5a - 14 = (a-7)(a+2)

Assuming the garden is a rectangle, the area is equal to length times width.

So 20x = 760.

Divide both sides by 20.

x = 760/20 = 38 ft

NEED HELP GIVING BRAINLIEST

Pie

For this case we have by definition, that the equation of a line in the slope-intersection form is given by:

$y = mx + b$

Where:

m: It's the slope

b: It is the cutoff point with the y axis

We need two points through which the line passes to find the slope:

$(0, -4)\\(1,0)$

We found the slope:

$m = \frac {y2-y1} {x2-x1}\\m = \frac {0 - (- 4)} {1-0} = \frac {4} {1} = 4$

So, the equation is of the form:

$y = 4x + b$

We substitute a point to find "b":

$-4 = 4 (0) + b\\-4 = b$

Finally, the equation is:

$y = 4x-4$
