---- = -------

10        10+10

Using cross products

6 ( 10+10) = x*10

6*20 = 10x

120 = 10x

Divide by 10

120/10 = x

12 =x

larisa86 [58]

Answer:

−5x − 2y − 3

Explanation:

2x + 5 − 3y − 7x + y − 8

= 2x + 5 + −3y + −7x + y + −8

[ Combine Like Terms ]

= 2x + 5 + −3y + −7x + y + −8

= (2x + −7x) + (−3y + y) + (5 + −8)

= −5x + −2y + −3

Keeping in mind that i² = -1,

\bf \begin{array}{c|ccccc}&#10;-1+i&&1&5&1&4\\&#10;&&&-1+i&-5+3i\\&#10;&&---&---&----&--\\&#10;&&1&4+i&-4+3i&#10;\end{array}\\\\&#10;-------------------------------\\\\&#10;(-1+i)(-4+3i)\implies 4-3i-4i+3\stackrel{-1}{i^2}\implies 4-3i-4i-3&#10;\\\\\\&#10;1-7i\\\\&#10;-------------------------------\\\\&#10;\begin{array}{c|cccccc}&#10;-1+i&&1&5&1&4\\&#10;&&&-1+i&-5+3i&1-7i\\&#10;&&---&---&----&---\\&#10;&&1&4+i&-4+3i&\boxed{5-7i}&\leftarrow remainder&#10;\end{array}


recall that a factor of the expression, gives a remainder of 0, and this one doesn't.
