Answer:
x² + 10x + 25
Explanation:
Before we begin, remember the following:
(a + b)(a + b) = (a + b)² = a² + 2ab + b²
Now, for the given we have:
(x + 5)(x + 5)
We can note that the two brackets are identical.
Therefore, we can apply the above rule as follows:
(x + 5)(x + 5) = (x + 5)²
= (x)² + 2(x)(5) + (5)²
= x² + 10x + 25
Hope this helps :)
Answer:
B
Step-by-step explanation:
Answer:
Yes!
The solution to the equation is n = 2
Step-by-step explanation:
Given the equation
remove the parentheses
Add 3 to both sides
Simplify
Add 2n to both sides
Simplify
Divide both sides by 6
Simplify
Therefore, the value of n = 2.
Hence,
Yes!
The solution to the equation is n = 2
