Answer:
In algebra, like terms are terms that have the same variables and powers. The coefficients do not need to match.
Unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers. The order of the variables does not matter unless there is a power. For example, 8xyz2 and −5xyz2 are like terms because they have the same variables and power while 3abc and 3ghi are unlike terms because they have different variables. Since the coefficient doesn't affect likeness, all
Answer:
<u>2 </u>sack of cement is required to cover Joel's entire floor.
Step-by-step explanation:
Given:
A sack cement can cover area = 45 sq. ft
Length of Joel floor = 8 ft
Width of Joel Floor = 7 ft
We will first find the Area of Joel's Floor
Area is the Product of length and width.
Area of the Floor =
Substituting the values we get;
Area of the Floor =
Now Given:
1 sack of cement cover area = 45 sq ft
Number of sack cement required to cover area = 56 sq. ft.
By Using Unitary method we will find the same.
∴ Number of sack cement required =
Since Sack of cement cannot be in point value hence we can say 2 sack cement is required.
Hence we can say 2 sack of cement is required to cover Joel's entire floor.
5 * 8/45=8/9
8/9 * 3/40=1/15
1/15
