Answer:
m=4
Step-by-step explanation:
4m-4-8=-2m+12
Combine like terms
4m-12 = -2m +12
Add 2m to each side
4m+2m -12 =-2m +2m+12
6m-12 = 12
Add 12 to each side
6m-12+12 =12+12
6m =24
Divide by 6
6m/6 =24/6
m =4

Answer:
25 ft²
Step-by-step explanation:
The hypotenuse =
= 13 ft
the side with area 144 ft² =
= 12 ft
Using Pythagoras' identity to find the third side x ( smallest )
x² + 12² = 13²
x² + 144 = 169 ( subtract 144 from both sides )
x² = 25 ( take the square root of both sides )
x =
= 5
Thus area of smallest side = 5² = 25 ft²
