Answer:

  see below

Step-by-step explanation:

<em>Which of the equations from part A represent adding two rational numbers?</em>

  Equations A, C, E

<em>What hypothesis can you make about the sum of two rational numbers?</em>

  The sum of two rationals will always be rational

<em>Will the addition result in a rational or an irrational number?</em>

  Our hypothesis is that the result is always rational. This can be justified by the fact that the sum of two rationals a/b + c/d, where a, b, c, d are integers and bd≠0, is (ad+bc)/(bd), a rational, based on closure of integers for multiplication and addition.

<em>Which equations represent the sum of a rational and an irrational number?</em>

  Equations B, F

<em>What hypothesis can you make about the sum of an irrational and a rational number?</em>

  The sum of a rational and irrational number is always irrational.

Solve for x in the equation x^2 + 2x+ 1 = 17.
muminat

Answer:

first, subtract 17 on both sides: x²+2x-16=0

this cannot be factored, so use the quadratic formula to solve for x:

b²-4ac=2²-4(10(-16)=4+64=68

√68=2√17

so x=(-2+2√17)/2 or x=(-2-2√17)/2

x=-1+√17 or x=-1-√17
