the area of square garden is 9a² + 12a +4 Square units.which expression represents the length of the side of the garden?
Answers
Answer:
Simple math.
First of all, you need to factor the expression
4x² +12x + 9
This will be a trial and error method.
Since you have a given choice, it will be obvious to know the right answer. We are talking about squares here
So
(2x + 3) will be the right one. Since only the 2x times itself will give us 4x^2
Remember Area of square is equal to side squared. or A = a^2
let's check:
2x + 3
2x + 3
-------------------
6x + 9 -> (2x + 3) * 3
4x^2 + 6x -> (2x + 3) * 2x
-------------------
4x^2 + 12x + 9 -> correct
I hope it helps

Learning Task 2: Perform the indicated operation to solve the following
Answer:
3a + √12a + 2
Step-by-step explanation:
take length as X
area of a square = X × X which is equal to X^2
therefore,
X^2 = 9a² + 12a +4
X = 3a + √12a + 2
