B)(x+10).(x-6)=x²-6x+10x-60
x²+4x-60
C)(x+15).(x-4)=x²-4x+15x-60
x²+11x-60
D)(x+20).(x-3)=x²-3x+20x-60
x²+17x-60
But A,
(x+12)(x-5)=x²-5x+12x-60
x²+7x-60
A, is the correct answer..
GOOD LUCK!
Answer: This type of sampling is Simple Random Sampling
Answer:
18
Step-by-step explanation:
1/3 of 27 is 9 so 2/3 is 18
.35x=40
/.35 /.35
X= 40/.35
X = 114.2857
X=3.5 add 10 and divide by 8
