Answer:
x = 4, x ≠ -1
Step-by-step explanation:
√3x + 4 = x
(√3x + 4)² = x² (Square both sides to get rid of the radical.)
3x + 4 = x²
0 = x² - 3x - 4 (Set everything to 0 by moving everything to one side.)
0 = (x - 4)(x + 1) (Factor.)
x = 4 x = -1
Now we need to check for extraneous solutions:
√3(4) + 4 = 4
√12 + 4 = 4
√16 = 4
4 = 4
√3(-1) + 4 = -1
√-3 +4 = -1
√1 = -1
1 ≠ -1
-1 is an extraneous solution.
Find the surface area of one side and multiply it by 6
Answer: -4.5
Step-by-step explanation:
Answer:
The correct option is C
Step-by-step explanation:
(x^3 +12x^2 +38x +26) / (x+4)
Use the coefficients of dividend.
And the divisor is -4:
Bring down 1 and multiply it by -4 and add to 12
12-4 = 8
Now multiply 8 by -4 = -32
48-32 = 6
Now multiply 6 by -4 = -24
26-24= R2
1 12 38 26
-4 -32 -24
_______________
1 8 6 R2
Thus the correct option is C ....
