Isolate the variable by dividing by 8. The answer will be A, x is greater than or equal to -4.
Answer:
n = ±6 .
Step-by-step explanation:
A quadratic equation is given to us and we need to find out the solution of the given equation . The given equation is ,
Subtracting 18 both sides ,
Multiplying both sides by -2 ,
On simplyfing , we get ,
Putting squareroot both sides ,
This equals to ,
<u>Hence</u><u> the</u><u> </u><u>value</u><u> of</u><u> </u><u>n </u><u>is </u><u>±</u><u>6</u><u> </u><u>.</u>
Hi,
1) D

2) C
Working:
144 cookies * 8 batches = 864 cookies
864 divided into boxes of 8 = 864 / 8 = 108
Answer:
In my own opinion i time 104 and 72and if gives me7488
3x27=81 so 81 is a multiple of 3
there is no integer x for which 4x=46 so 46 is not a multiple of 4
there is no integer x for which 7x=55 so 55 is not a multiple of 7
72 = 8*9 so 72 is a multiple of 9
there is no integer x for which 6x=45 hence 45 is not a multiple of 6
