Answer:
x=
Step-by-step explanation:
5(x+6)+11=25
Use the distributive property to multiply 5 by x+6.
5x+30+11=25
Add 30 and 11 to get 41.
5x+41=25
Subtract 41 from both sides.
5x=25−41
Subtract 41 from 25 to get −16.
5x=−16
Divide both sides by 5.
x=-16/5
Fraction -16/5 can be rewritten as -16/5 by extracting the negative sign.

Answer:
A = 10.27cm²
Step-by-step explanation:
Let's represent the width as x,
therefore since the length is 4 more than 3 times the width, it can be represent as 3x + 4, Perimeter = 18.4cm
Perimeter of a rectangle = 2(L + B)
width = 1.3cm
Length = 3x + 4 = 3*1.3 + 4 = 7.9cm
Area of a rectangle = length x width
A = 7.9 * 1.3 = 10.27cm²
