Answer:
x= -8 x=2
Step-by-step explanation:
x^2 +6x - 6 = 10
Subtract 10 from each side
x^2 +6x -16 =0
Factor what 2 numbers multiply to -16 and add to 6
8*-2 = -16
8-2 = 6
(x+8) (x-2) =0
Using the zero product property
x+8 =0 x-2 =0
x= -8 x=2
The solution is -0.609611 and -1.64, I do not think you can simply find this by factoring but the only way is graphing it
Note: to round to the nearest ten, look to the first place digit. if it is 5 or greater, round up, if 4 and lower, round down
<em>124 rounded to the nearest ten = 120</em>
<em>38 rounded to the nearest ten = 40</em>
<em>71 rounded to the nearest ten = 70</em>
<em>207 rounded to the nearest ten = 210
120 + 40 + 70 + 210 = 120 + 110 + 210 = 230 + 210 = 440
440, or C </em>is your answer
hope this helps
The best answer would be be C.20
