Answer:
x = 16
Step-by-step explanation:
(5x + 12)° + (6x - 8)° = 180°
(5x + 12 + 6x - 8)° = 180°
(11x + 4)° = 180°
11x + 4 = 180
11x = 180- 4
11x = 176
x = 176/11
x = 16
We have
.
First let us factor the 2 to obtain,

We can now see clearly that the expression inside the parentheses is a difference of two squares.
We now write the 4 as 2². So that we obtain the expression,

Recall that

Hence our expression becomes,

Therefore, when factored completely,

Answer:
A=144cm²
Length: 36cm
Width: 4cm
Step-by-step explanation:
36 x 4 = 144 cm
