<em>Answer:</em>

<em>(r + 9)(r - 3)</em>

<em>Step-by-step explanation:</em>

<em>r² + 6r - 27 =</em>

<em>= r² + 9r - 3r - 27</em>

<em>= r(r + 9) - 3(r + 9)</em>

<em>= (r + 9)(r - 3)</em>

Answer:

y = -x - 2

Step-by-step explanation:

Find two points on the line

(0, -2)

(4, -6)

(Y2-Y1)/(X2-X1) = gradient of the line

Where (X1,Y1) = (0, -2) and (X2,Y2) = (4, -6)

(-6--2)/(4-0)

(-6+2)/4

(-4)/(4)

-1

Y = (-1)X + c

Substitute either set of coordinates in to find c.

(0, -2)

Y = (-1)X + c

-2 = (-1)0 + c

-2 = 0 + c

-2 = c

(4,-6)

Y = (-1)X + c

-6 = (-1)4 + c

-6 = -4 +c

-6 + 4 = c

-2 = c

Y = -X -2

Answer: 100

Hi!

ok so the Pythagorean theorem is

$c=\sqrt{x} a^2+b^2=\sqrt{x} 8^2+6^2=10$

so the other side is 10.

the square 8 is 8*8

and square 6 is 6*6

so the other square is 10*10=100.

so the area of the blank square is 100.
