Symbolab helps a lot!!! I got the answer y=4/5×+1/2
0.5
Given data
Now,
4x+3y=8xy......(i)
6x+5y=13xy.......(ii)
Multiply by 5 in equation (i) and by 3 in equation (ii)
20x+15y=40xy.....(iii)
18x+15y=39xy.....(iV)
Solving above equation (iii) and (iv)
2x=xy
y=2
Now, putting the y=2 in equation (i)
4x+3(2)=8x(2)
4x+6=16x
6=12x
x=0.5
Value of x=0.5
Pythagorian theorem:
7^2=13+b^2 -> b^2=49-13=36
The square root of 36 is obviously 6.
So, the other leg has a length of 6 inches

Yes
Using the Pythagorean theorem, you would square 8, 15, and 17. 8^2 is 64. 15^2 is 225. If you add those, you get 289. Now, 17^2 is 289. Because 289=289, it is a square triangle.
