Find the area and perimeter <br> please help me :)

Katarina [22]

Answer:

Perimeter: 44

Area: 96

Step-by-step explanation:

Perimeter - Just add all the sides together, 4 + 10 + 12 +7 + 8 + 3.

(The 8 and the 3 are apart of the sides that are not labeled. Since 12 - 4 = 8, and 10 - 7 = 3, That's where these numbers come from.)

Area - 4 * 10 = 40,

+ 8 * 7 = 56,

--------------------------------

= 96

I hope this helps :)

(19,-9) (-7,-15) in slope intercept form

never [62]

Answer:

$y=\frac{3}{13}x-\frac{174}{13}$

Step-by-step explanation:

slope:

$m=\frac{-15-(-9)}{-7-19} =\frac{-15+9}{-26} =\frac{-6}{-26} =\frac{3}{13}$

Equation, with the point (19, -9):

$y-(-9)=\frac{3}{13} (x-19)$

$y+9=\frac{3}{13} x-\frac{57}{13}$

$y=\frac{3}{13} x-\frac{57}{13} -9$

$-9=-9(\frac{13}{13} )=-\frac{117}{13}$

$y=\frac{3}{13}x-\frac{174}{13}$

Hope this helps
