for the first term:
n= 1 there is 1 item
n=2 there are 2+1 = 3 items
n = 3 there are 3+2+1 = 3+2 = 6 items
n = 4 there are 4+3+2+1 = 4+6 = 10 items
We are adding the "n" term each time
n = 5 10+5 = 15
n= 6 15+6 = 21
n = 7 21+7 = 28
n = 8 28+8 = 36
There would be 36 items in the 8th step
Answer:
The square with side 5 centimeters have a greater area.
Corrected question;
Which has the greater area: a 6‐centimeter by 4.12‐centimeter rectangle or a square with a side that measures 5 centimeters?
Step-by-step explanation:
The Area of a rectangle can be written as;
Area A = length × breadth
Given;
Length = 6 cm
Breadth = 4.12 cm
Substituting the values;
Area of rectangle = 6cm × 4.12cm = 24.72 cm^2
For the square;
Area of a square = length × length
Given;
Length = 5 cm
Substituting the values;
Area of the square = 5cm × 5cm = 25 cm^2
Since 25 cm^2 is greater than 24.72 cm^2
The square has a greater area.
Answer: x=7/5 or 1 2/5
Step-by-step explanation:
Given
x+3/5=2
Subtract 3/5 on both sides
x+3/5-3/5=2-3/5
x=10/5-3/5 (This is to convert 2, as a integer, to a fraction in order to ease the
x=7/5 operation)

Answer:
x=4
Step-by-step explanation:
4x+2(x+6)=36
distribute the 2
4x+2x+12=36
combine like variables
6x+12=36
subtract 12
6x=24
divide by 6
x=4
