PLEASE HELP DUE NOW!!!<br> WILL MARK BRAINLIEST!!!

Sav [38]

Answer:

(-5, -8)

Step-by-step explanation:

$- 9x + 5y = 5 \\ - 5x + 5y = - 15$

$- 9x + 5y = 5 \\ 5x - 5y = 15$

$- 4x = 20$

$- x = 5$

$x = - 5$

$-5( - 5) + 5y = - 15$

$25 + 5y = - 15$

$5y = -40$

$y = -8$

W - width
l - length
p - perimeter

The perimeter is 72 cm (p=72).
The length is twice the width (l=2w).
The formula for perimeter is 2w+2l=P.

$p=72 \\
l=2w \\ \\
2w+2l=p \\
2w+2 \cdot 2w=72 \\
2w+4w=72 \\
6w=72 \\
w=12 \\ \\
l=2w=2 \cdot 12 =24$

Check the answer:
$2 \cdot 12 + 2 \cdot 24 \stackrel{?}{=} 72 \\
24+48 \stackrel{?}{=} 72 \\
72 \stackrel{?}{=} 72 \\ \hbox{true}$

The length of the photo is 24 cm, the width of the photo is 12 cm.
