yarga [219]

well, we can say that 1 hour is 100%, what is 2/5 hr off of it in percentage?

$\begin{array}{ccll} hour&\%\\ \cline{1-2} 1 & 100\\ \frac{2}{5}& x \end{array} \implies \cfrac{1}{~~ \frac{2}{5}~~}=\cfrac{100}{x}\implies \cfrac{5}{2}=\cfrac{100}{x} \\\\\\ 5x=200\implies x=\cfrac{200}{5}\implies x=40$

A square has side length represented by X +4 inches write an expression to represent the area. Express your answer as a trinomia

romanna [79]

Answer:

$A=(x^2+16+8x)\ \text{inches}^2$

Step-by-step explanation:

Given that,

The side length of a square, l = (x+4) inches

We need to find an expression to represent the area of the square.

The area of a square is given by :

$A=\text{side}^2$

So,

$A=(x+4)^2\\\\A=(x^2+16+8x)\ \text{inches}^2$

So, the area of the square is $(x^2+16+8x)\ \text{inches}^2$ .
