Answer: Shorter leg = 6 inches
Longer leg = 6+2 = 8 inches
Step-by-step explanation:
Let the shorter leg bw represented by x.
Therefore, the longer leg will be x+2.
The hypothenuse is 10inches
We should note that in Pythagoras theorem, the square of the longer and shorter side equals the square of the hypothenuse. This will be:
x² + (x+2)² = 10²
x² + x² + 4x + 4 = 100
2x² + 4x = 100 - 4
2x² + 4x = 96
2x² + 4x - 96 = 0
x² + 2x - 48 = 0
x² + 8x - 6x - 48 = 0
x(x + 8) -6(x + 8) = 0
x - 6 = 0
x = 0+6.
x = 6
Shorter leg = 6 inches
Longer leg = 6+2 = 8 inches

Answer:
sure
Step-by-step explanation:
width = 2n+8
length = 3 * width = 3*(2n+8) = 6n+24
Perimeter = 2(l+w)
= 2( 6n+24 + 2n+8)
= 2( 8n+32)
96 = 16n +64
-64 -64
--------------------------------------
32 = 16n divide by `16
2 = n
width = 2n+8 = 2*n + 8= 4 + 8 = 12
length = 3*width = 3*12 = 36
