Answer:
Extremely large and small numbers that have many zeros are long to write and take up a lot of room. So, by using scientific notation a number can be written shorter. For example, numbers such as 295,000,000,000 can be shortened to 2.95x
. This is easier to write and understand. This is why the scientific notation is used over standard.
obtain from (a number) another that contains the first number a specified number of times. 2 times 2 can also be 2+2
6x3 = 6+6+6
Answer:
1. Area of rectangular rug is 
2. Area of triangular room is 
Step-by-step explanation:
This problem bothers on the mensuration of flat shapes, rectangle and triangle.
step one
let us start by solving for the area of the rectangular rug
given data
Area A = ?
Length l = 11 ft
Width w= 10 ft
we know that the area of a rectangle is expressed as

substituting our given data we have

step two
let us solve for the area of the triangular room
given data
Area A = ?
base b = 30 ft
height h= 22 ft
we know that the area of a triangle is expressed as

substituting our given data we have

Y - 4 + 8
y +4
x2 + 4x + 4
x + 2 + 2
x + 4
x2 + 2x+ 1
x + 2 + 1
x + 2
j2 + 40j + 400
j + 20 + 200
j + 220
25n2 + 40np + 16p2
25n + 20p + 16p2
25n + 10 + 4
25n + 14
