15. (2•l)+(2•w)=38.
(2•l)+8=38.
Subtract 8 from both sides which leaves (2•l)=30.
Divide by 2 from both sides and that leaves 15.

Write the equation of the line that passes through the points (-6, -9) and (7, 7).
Rus_ich [418]

Answer:

\displaystyle y + 9 = \frac{16}{13} ( x + 6 )

Step-by-step explanation:

The point-slope form of the equation of a line is:

y - k = m ( x - h )

Where m is the slope and (h,k) is a point through which the line passes.

Given a line passes through points A(x1,y1) and B(x2,y2), the slope can be calculated with the equation:

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

We are given the points (-6,-9) and (7,7), thus the slope is:

\displaystyle m=\frac{7+9}{7+6}=\frac{16}{13}

Now we apply the point-slope formula using the point (-6,-9):

\mathbf{\displaystyle y + 9 = \frac{16}{13} ( x + 6 )}

This equation is expressed in the required format

Gala2k [10]

Answer:

11\sqrt{2}

Step-by-step explanation:

The given shape is a right triangle, to find the value of x we can use Euclidian Theorem:

x^2 = 14*(14+4)

x^2 = 280 find the root for both sides

x = 11\sqrt{2}
