Using Intercept theorem/Intercept theorem
![\frac{6}{6+15} =\frac{9}{9+x}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B6%2B15%7D%20%3D%5Cfrac%7B9%7D%7B9%2Bx%7D)
6(9+x)=9*21
54+6x=189
6x=135
x=22.5
At least I think so
Answer: x = 40 and y = 40
Step-by-step explanation:
We can write the equation for the area as: x*y = 1600
We can write the equation for the perimeter as: 2x + 2y = 160
An easy way to solve a question like this is to graph both equations on a graphing calculator, if you don't have one on you you can use Desmos
Graph both: y = 1600/x
and
y = 80 - x
Turns out you get x = 40 and y = 40
Answer:
x-int: (2, 0)
y-int: (0,8)
(8-0)/(0-2)= 8/-2= -4
y - 0 = -4(x - 2)
y = -4x + 8
