You must have 4 terms for factoring by grouping to be easier to use.

For example...
x^2 + 10x + 2x + 20
(x^2 + 10x) + (2x + 20)
x(x+10) + 2(x+10)
(x+2)(x+10)

A rectangle has a perimeter of 116 centimeters and a length of 26 centimeters what is the width of the rectangle
notsponge [240]

Answer:

The width of the rectangle=32 cm

Step-by-step explanation:

We are given that

Perimeter of rectangle, P=116 cm

Length of rectangle, l=26 cm

We have to find the width of the rectangle.

We know that

Perimeter of rectangle, P=2(l+b)

Where l=Length of rectangle

b=Width of rectangle

By using the formula

116=2(26+b)

\frac{116}{2}=26+b

58=26+b

58-26=b

32=b

Hence, the width of the rectangle=32 cm

ElenaW [278]

Answer: 1/6 package of pepperoni

Step-by-step explanation:

There were three pizzas and Mom used 1/2 package of pepperoni on all of them in an equal amount.

The fraction that each pizza got is therefore this 1/2 divided by the number of pizzas it was used on which is three.

= 1/2 ÷ 3

This is the same as:

= 1/2 * 1/3

= 1/6 package of pepperoni
