42-x=58
or, -x=58-42
with change in side sign also chamges we change sides to make like terms in one side and unlike in amother side.
or, -x= 16
or,x=-16.
therefore x=-16...

Answer: The width of the rectangle is 10.2 inches, the perimeter is 71.4 inches, the area is 260.1 inches.
Step-by-step explanation:
25.5/5=5.1
5.1*2=10.2
The width is 10.2 inches
25.5*2+10.2*2=71.4
The perimeter is 71.4 inches
20.5*10.2=260.1
The area is 260.1
Simplifying
f(x) = x2 + 8x + -3
Multiply f * x
fx = x2 + 8x + -3
Reorder the terms:
fx = -3 + 8x + x2
Solving
fx = -3 + 8x + x2
Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Divide each side by 'x'.
f = -3x-1 + 8 + x
Simplifying
f = -3x-1 + 8 + x
Reorder the terms:
f = 8 + -3x-1 + x
