Answer: −3x²−15x−30
Step-by-step explanation: use Square of Sum (a+b)²=a²+2ab+b²
−3(x²+2x×3+3²)-3+3x
−(3x² +18x+27)−3+3x
−3x²−18x−27−3+3x
−3x²+(−18x+3x)+(−27−3)
−3x²−15x−30
Hope this helps, now you know the answer and how to do it. Stay healthy and safe and HAVE A BLESSED AND WONDERFUL DAY! :-)

Answer:
The perpendicular line 4x − 5y = 20 has a slope of 4/5 and as such, the slope of the required line = -5/4
(y - 3)/(x + 4) = -5/4 simplify to get the required equation: 5x + 4y + 8 = 0
1 pound = 16 ounces
1 ounce =1/16 pound
Answer:
1/3
Step-by-step explanation:
5/6-x=1/2
x=5/6-1/2
x=5/6-3/6
x=2/6
simplify
x=1/3
