The correct answer is , B ) acute
The answer is D all of the above
Answer:
n = -4/9
Step-by-step explanation:
8n + 9 = -n +5
Add n to each side
8n+n + 9 = -n+n +5
9n +9 = 5
Subtract 9 from each side
9n+9 - 9 = 5-9
9n /9 = -4/9
Divide each side by 9
n = -4/9
The value of expression is,
⇒ (2m - 8)² = 4m² - 24m + 64
An algebraic equation with the second degree of the variable is called an Quadratic equation.
Given that;
The expression is,
⇒ (2m - 8)²
Now,
We know that,
The formula is,
⇒ (a - b)² = a² - 2ab + b²
Hence, We get;
⇒ (2m - 8)² = (2m)² - 2 × 2m × 8 + (8)²
= 4m² - 24m + 64
Thus, The value of expression is,
⇒ (2m - 8)² = 4m² - 24m + 64
