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>
144 inches because if you multiply 12 feet by 12 inches (12 inches is equal to one foot) it gives you 144 inches.
A bi-millennium means two (bi) times thousand of years (millenium), this means that a bi millennium has 2000 years in it: two thousand years.
The origin of this word is latin: because of this it also has the plural of "bimillennia" <span />
