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
What area of math is this,I may be able to help?
3. you cannot simplify √30
When you evaluate the problem you end up with 204100
Scientific Notation: 2.041 x 10^5
20% off means you paid only 80% of the original price.
0.8x=40
x=40÷0.8=50
so the original price is 50
