If x is width of one square, then width of board is 8x.

Area of a square = x^2 = 13
$x = \sqrt{13}$

$8x = 8\sqrt{13}$

Answer:
$8\sqrt{13} cm$

Answer:

a.

${ \tt{3x - 6y + 8 = 0}} \\ { \tt{ 6y = 3x - 8}} \\ { \boxed{ \bf{y = \frac{1}{2} x - \frac{4}{3} }}}$

b.

${ \tt{ - 2x - 5y - 2 = 0}} \\ { \tt{5y = - 2x + 2}} \\ { \boxed{ \bf{y = - \frac{ 2}{5} x + \frac{2}{5} }}}$

Answer:

12

Step-by-step explanation:

These triangles are similar using the AA theroem. This means there sides are in corresponding proportion.

Side AR and Side TE are corresponding. Use this proportion.

$\frac{6}{8}$

This side the triangle SAR side lengths are 3/4 of side lengths of triangle SET.

We know that RS+ST=21

And that RS=3/4(ST).

$\frac{3}{4} x + x = 21$

$1.75x = 21$

x=12.

Side ST is 12
