Answer:
25
Step-by-step explanation:
The number that needs to be added is the square of half the x-coefficient:
(-10/2)^2 = 25
_____
Adding that gives ...
(x -5)^2 = 32
x = 5 ± 4√2
Answer:
x= -8
Step-by-step explanation:
2x+3x-12=8x+12
5x-12=8x+12
5x-8x=12+12
-3x=24
24/-3
x= -8
Answer:
There is no following, we have data of all the people
Step-by-step explanation:
There where Sixty-five salespersons asked and the if we add all the persons that where asked it is the same. So there is no following
Fourteen people answered that they generally sell two cars; 14
nineteen generally sell three cars; 19
twelve generally sell four cars; 12
nine generally sell five cars; 9
eleven generally sell six cars 11
Adding 14+19+12+9+11=65 persons
I hope this helps you
square root of (4x+41)=x+5
4x+41>=0
x >= -10.25
(square root of4x+41)^2=(x+5)^2
4x+41=x^2+10x+25
x^2+6x-16 =0
x +8
x -2
(x+8)(x-2)=0
x= -8
x= 2 extraneous
