Answer:
3, 5, 7, 9, 11, .........
Step-by-step explanation:
Given
= n(n + 2) , then
S₁ = 1(1 + 2) = 1(3) = 3 ⇒ a₁ = 3
S₂ = 2(2 + 2) = 2(4) = 8
S₃ = 3(3 + 2) = 3(5) = 15
Thus
a₂ = S₂ - S₁ = 8 - 3 = 5
a₃ = S₃ - S₂ = 15 - 8 = 7
The first 3 terms are 3, 5, 7
This is an AP with common difference d = 2, then
a₄ = a₃ + 2 = 7 + 2 = 9
a₅ = a₄ + 2 = 9 + 2 = 11
and so on
Answer: subtraction
Reasoning: You need to subtract 3 from both sides first.
The total amount of paint needed is 15 quart and it cost $41.25.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
0.0015 quart of paint to cover 1 square inch.
Let the area of the rectangle be 10000 in², hence:
Amount of paint = 0.0015 quart per in² * 1000 in² = 15 quart
Cost of paint = $2.75 per quart * 15 quart = $41.25
The total amount of paint needed is 15 quart and it cost $41.25.

Make an equation.
80% = 0.8
'of' is multiplication
'what number' is 'x'
'is' is an equal sign
0.8 * x = 64
0.8x = 64
Divide 0.8 to both sides:
x = 80
1.) 14
2.) 10
3.) 7 : 6
5.) 80
6.) 8 : 7
these are all i have the time to answer i'm sorry!
