Answer:
(2x +5y)(2x − 5y) =
Step-by-step explanation:
(2x +5y)(2x − 5y) is the given equation.
Now, the <u>ALGEBRAIC IDENTITY</u> states that:
Here, comparing a = 2x and b = 5y,
we get (2x +5y)(2x − 5y) =
on further solving the right side, we get
(2x +5y)(2x − 5y) =
It’a the third , and can I have the brainliest too
Answer:
I wish I know the answer
Step-by-step explanation:
lemme try again
I think 30??
Because if there are twice as much girls then 10*2=20 girls and 10 boys. So 20+10=30
