Answer:
choice C. Perfect square trinomial is correct.
Step-by-step explanation:
We need to find the pattern which is represented by the polynomial .
To find that pattern, we need to factor
which is a perfect square.
Hence choice C. Perfect square trinomial is correct.
Answer:
Step-by-step explanation:
First, turn the word problem into an equation:
n(a number) was divided by 2
followed by this quotient beying multiplied by 4
*4
the product was added to 9
*4+9
the total sum was 25
*4+9 = 25
use PEMDAS to solve the equation
subtract 9 on both sides
*4 = 16
cancel the 2 and the 4 using factorization
n*2 = 16
divide 2 on both sides
n = 8
