Simplify with foil (w + x )(w + x )

Step-by-step explanation:

Given the expression , which indicates the multiplication of two binomials, you can simplify it with FOIL:

Multiply:

The first terms (w by w).

The outside terms  (w by x).

The inside terms together (x by w).

The last terms together (x by x).

Then, you get:

Adding like terms, you get:

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
