Answer:
Step-by-step explanation:
x² - 12x + a = (x + b)²
x² - 12x + a = x² + 2xb + b²
-12 = 2b and a = b²
b = -6
a = b² = 36
D
The andwer is d
D is yeh answer
I don’t really understand what your question is
Answer: n = -4
3n - 3 = 4n + 1
Add 3 to both sides
3n = 4n + 4
Subtract 4n from both sides
-n = 4
Divide by -1 on both sides
n = -4
Evaluating an expression consists of just replacing the letter by its value and do the calculus.
We have the expression 14b - 513. And by hypothesis, b = 44.
So just replace b by 44.
14b - 513 = 14*44 - 513 = 616 - 513 = 103.
So 14b - 513 = 103 (answer b) when b = 44.
Hope this helps! :)
