None of the answers provided are equivalent
Step-by-step explanation:
To solve it would be best to simplify each of the expressions you have listed by combining like terms all the x^2 terms have been bolded, the x terms italicized, and the constant terms are underlined
(<em>4x</em> <u>+ 1.2</u>) + (2x ^ 2 <em>- 6x</em> <u>+ 5</u>) = 2x ^ 2 <em>- 6x</em> <u>+ 6.2</u>
(x ^ 2 <em>- 5x</em> +<u> 13</u>) + (x ^ 2 <em>+ 3x </em><u>- 6</u>) = 2x^2 <em>-2x </em><u>+7</u>
(4x ^ 2<em> - 6x</em> <u>+ 11</u>) + (2x ^ 2<em> - 4x</em><u><em> </em></u><u>+ 4</u>) = 6x^2 -<em>10x </em><u>+15</u>
(5x ^ 2 <em>- 8x</em> <u>+ 120</u>) + (- 3x ^ 2 <em>+ 10x</em> <u>- 13</u>) = 2x^2 <em>+ 2x</em> <u>+ 107</u>

Answer:
1.92
Step-by-step explanation:
mean ( or average ) = sum of values / the total number of values
so the sum of the values is counting each value
doing so we would get 46
we then add the number of values given which would be 24
so we have mean = sum of values / # of values
and we have sum of values = 46 and # of values = 24
so mean = 46/24 = about 1.92
