Answer:

x=2

Step-by-step explanation:

Step-by-step explanation:

a straight line equals to 180

27x+42+23x+38=180

(combine like terms)

50x+80=180

(subtract 80 from 180)

50x=100

(divide 50 by 100)

x=2

Answer:

x = 2

Step-by-step explanation:

Since these two angles are complimentary, that means that they add up to 180 degrees.

<u>Step 1:  Make an equation </u>

<em>(27x + 42) + (23x + 38) = 180 </em>

<u>Step 2:  Combine like terms </u>

<u>27x</u> + 42 + <u>23x</u> + 38 = 180

<em>50x + 80 = 180 </em>

Step 3:  Subtract 80 from both sides

50x + 80 - 80 = 180 - 80

50x = 100

Step 4:  Divide 50 from both sides

50x / 50 = 100 / 50

<em>x = 2 </em>

Answer:  x = 2

Select the correct answer.<br> Which expression is equivalent to this polynomial?<br> x2 + 8
Svetlanka [38]

Answer:

D ( x -2i sqrt(2)) ( x+ 2i sqrt(2))

Step-by-step explanation:

x^2 + 8

We want to factor so rewrite as squares

x^2 + (2sqrt(2))^2

Rewrite with a subtraction sign i^2 = -1

x^2 - (2*i*sqrt(2))^2

This is the difference of squares

a^2 - b^2 = ( a-b) (a+b)

( x -2i sqrt(2)) ( x+ 2i sqrt(2))

Your solution set is (x,y)
Your x coordinate is always first. 
Since your x is -5 and your y is -6.
The solution set is (-5,-6)
