carlosego genius 11.6k answer 175.7m people helped the perimeter is the sum of the sides: P=(x-7) +(x+1)+(x) rewriting: P=3x-6 the area is giving by:A=(1/2)*(x-7)*(x) the area and the perimeter are the same: (1/2)*(x-7)*(x)=3x-6 rewriting: (x-7)*(x)=6x-12 x^2-7x-6x+12=0 x^2-13x+12=0 polynomial of degree 2, therefore there are 2 possible solutions. Viable solution. Viable solution: x=12 sides of triangle: 5 12 13
Answer:
Step-by-step explanation:
In similar triangles corresponding triangles are in same ratio.
![\frac{15}{5}=\frac{12}{y}](https://tex.z-dn.net/?f=%5Cfrac%7B15%7D%7B5%7D%3D%5Cfrac%7B12%7D%7By%7D)
Cross multiply,
15 * y = 12 * 5
y = ![\frac{12*5}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B12%2A5%7D%7B15%7D)
y = 4
In order
1) given
2) multiplication property of equality
3) distribution property of equality
4) addition or subtraction property of equality
5) subtraction property
In the second one, they are multiplying both sides to get rid of the fraction
In the third one, they are showing the equation after distributing 2 through the parenthesis
In the fifth one, they are subtracting 4x from both sides to get x = 2
I hope this helps!
