If ΔABC ≅ ΔDEF, then what corresponding parts are congruent?
GaryK [48]

The corresponding parts that are congruent are (a) AB and DE

<h3>How to determine the congruent parts?</h3>

The statement ΔABC ≅ ΔDEF means that the triangles ABC and DEF are congruent.

This implies that the following points are corresponding points:

A and D; B and E; C and F

When two corresponding points are joined together, the congruent parts are:

AB and DE, AC and DF, BC and EF

Hence, the corresponding parts that are congruent are (a) AB and DE

What is the value of the rational expression 2x^2+5x+9/x^2+2x-1 when x=-2
Sergio039 [100]

Answer:

The value of the Rational expression when x=-2 is: -7

Step-by-step explanation:

For this exercise is important to remember:

  • When a negative number is raised to an even power, the result will be positive.
  • The multiplication of signs:

       (+)(+)=+\\(-)(-)=+\\(-)(+)=-

Then, given the following Rational expression:

\frac{2x^2+5x+9}{x^2+2x-1}

You need to follow these steps in order to find its value when x=-2:

1. Substitute the given value of "x" (x=2) into the expression:

 \frac{2(-2)^2+5(-2)+9}{(-2)^2+2(-2)-1}

2. Evaluate and simplify:

\frac{2(4)+5(-2)+9}{4+2(-2)-1}=\frac{8-10+9}{4-4-1}=\frac{7}{-1}=-7
