what is that pls tell me in comments
Step-by-step explanation:
7hrs/ =x
21hrs 189
1323=7x
7 7
189=x
the speed of the boat in still water is 189
i got the answer by setting a proportion.
hope it work
No the square root of 16 is 4 which is a whole number therefore it is rational not irrational
Answer:
The equation that gave the solution provided is either
x² + 5x + 4 = 0 or k(x² + 5x + 4) = 0 where k = real number
Step-by-step explanation:
Although, the question isn't complete and the blanks to be filled aren't provided, Hence, we can work out a quadratic equation from the solutions for x given
The solutions for x include x = -4 or x = -1
x = -4 or x = -1
(x + 4) = 0 or (x + 1) = 0
So,
(x+4)(x+1) = 0
x² + 4x + x + 4 = 0
x² + 5x + 4 = 0
Hence, the equation that gave this solution is either x² + 5x + 4 = 0 or a constant multiple of the equation obtained; k(x² + 5x + 4) = 0
Hope this Helps!!!
Answer:
Given equation:
when we complete the square , we take half of the value of 8 , then square it, and added to the left sides, we get;
∵8 is the value
Notice that, we add this both sides so that it maintains the equality.
then;
[ ]
Simplify:
The number must be added to complete the square is,
