Answer:
Step-by-step explanation:
Typically when solving an equation with one variable, your objective is to isolate the variable on one side of the equation. This can be done adding/subtracting number to cancel them out on one side. You can also multiply/divide coefficients in order to isolate a variable.
Answer:
x = -4 ±3
x = -7,-1
Step-by-step explanation:
x^2 + 8x = -7
1/2 B ^ 2 = 16
x^2 + 8x + 16 = 16 -7
(x + 4) ^2 = 9
x + 4 = ±3
x = -4 ±3
x = -7,-1
The standard deviation of the numbers 14 22 6 9 11 23 15 18 20 12 is 5.67646 the mean is 15 and the standard deviation variance is 32.222.
1 1/12 i’m pretty sure is the answer
Answer: User got this. x=50+6/7 is the Answer.
Step-by-step explanation:
Step 1) Move all terms to the left:
(x+4)7/3-(128)=0
2) Multiply all the terms by the denominator
(x+4)7-128*3=0
3) Add all the numbers together, and all the variables
(x+4)7-384=0
4) Multiply parentheses
7x+28-384=0
5) Add all the numbers together, and all the variables
7x-356=0
6) Move all terms containing x to the left, all other terms to the right
7x=356
x=356/7
x=50+6/7
