Hence, the value of x is 1.

<h2>What is length?</h2>

Length is defined as the measurement or extent of something from end to end. In other words, it is the larger of the two or the highest of three dimensions of geometrical shapes or objects.

<h3>How to solve?</h3>

It can be observed that the given 2 triangles are congruent.

we know, for congruent triangles, the length of corresponding sides is equal.

Hence,

       AB = DE

       4x - 1 = x + 2

       3x = 3

       x=1

Therefore, the value of x is 1.

Svet_ta [14]

Answer:

Therefore, the following results are not possible:

A) green offspring only

Step-by-step explanation:

We know that feather color in budgies is determined by two different genes. For blue color are combinations yyBB or yyBb. For white color is combination yybb.  

By combining these two colors we can not get green and yellow.  

Because green and yellow colors are  in this form:

Green: YYBB, YyBB, or YYBb

Yellow: YYbb or Yybb.

Therefore, the following results are not possible:

A) green offspring only

B) yellow offspring only

D) green and yellow offspring.
