The difference between (3x+6y)(3x+6y) and (4x+9y)(4x+9y) is 7x² +36xy+45y²
<h3>What is an Expression ?</h3>
An expression is a mathematical statement which has variables , constants and mathematical operators simultaneously.
The expression given in the question is
(3x+6y)(3x+6y) and (4x+9y)(4x+9y)
the difference when (3x+6y)(3x+6y) is subtracted from (4x+9y)(4x+9y)
(4x+9y)(4x+9y) - (3x+6y)(3x+6y)
16 x² + 36xy+36xy +81y²-9x²-18x -18x -36y²
7x² +36xy+45y²
Therefore in simplest term , The difference between (3x+6y)(3x+6y) and (4x+9y)(4x+9y) is 7x² +36xy+45y²

If I put this into an equation it would look like 2x+2= 66. 66-2= 64. You do this because to get x you have to reverse the equation, but you have to do the number not connected to x first. Then 2x= 64. So you divide 64 by 2 which is 32. So Jordan is 32 years old. Hope this helped!
Answer:

Step-by-step explanation:

To find the GCF first list down the prime factors of each number then multiply the factors both have in common, or if the numbers have only one prime factor in common then that's the answer. to find the prime factors of a number just divide the number by prime factors in order.
in this question prime factors of the numbers are,
18=2×2×3
45=3×3×3
90=2×3×3×5
the common factors are 3 and 3. so now multiply 3 by 3= 9
answer=9
hope this helps....
