The answer is <span>16x2 − 8x + 1

To be a perfect square trinomial, the rule must be used:
(a - b)² = a² - 2ab + b²
Let's check all choices
A. a = 7x, b = 4
(7x - 4)² = 49x² - 56x + 16
B. a = 2a, b = 5
(2a - 5)² = 4a² - 20a + 25
C. a = 5b, b = √10
(5b - √10)² = 25b² - 10√10 b + 10
D. a = 4x, b = 1
(4x - 1)² = 16x² - 8x + 1
CORRECT
Answer:
= - 9x2+4x+2/4x-2
Step-by-step explanation:
Remove parentheses
its blank we need to find a number
step 1: = -/4x-2 (9x2+4x+2)
step 2: multiply fractions and there is your answer
9x2+4x+2/4x-2
Answer:
23/100 or 23/10
Step-by-step explanation:
2.3/1
(2.3 x 10) / (1 x 10) =23/10
find lcm (lowest common multiple) for 23 and 10
1 is the lcm for 23 and 10
23/10 is a simplest fraction for the decimal point number 2.3
