hello :
(x-4)²(x+3)² = -1
means : ((x-4)(x+3))² = - 1 this equation has no solutions in R
because for all x in R : ((x-4)(x+3))² ≥ 0
Answer:
The least possible quotient is 125.
Step-by-step explanation:
To do this we need to find the greatest 2 digit factor of 10,000.
10,000 = 2*2*2*2*5*5*5*5
So the greatest 2 digit number which will divide exactly into 10,000 is
= 2*2*2*2*5
= 80.
This will give the smallest quotient: 10,000 / 80 = 125.
Number 6 is incorrect. Remember when you see -(-1) that is addition because you are subtracting a negative from a negative so you take the negative sign away and you have a positive. The correct answer to 6 is -75. For number 9 the first thing that you are gonna do is distribute that negative sign to the -12 in parentheses. This will make it a positive 12 which leaves you with
-8+12-31=-27
Next for number 12 you will distribute the - sign onto the -9 in parentheses and the -16 in parentheses. This will leave you with -16+9+16=9
Hope that this helped!
