Which of the following constants can be added to x2 - 3x to form a perfect square trinomial?
jeka57 [31]

<em>Answer:</em>

<em>2 whole 1/4</em>

<em>Step-by-step explanation:</em>

<em>When forming a perfect square trinomial you need to "complete the square". </em>

<em>All of the steps to completing the square when solving an equation: </em>

<em>1.  The leading coefficient must be 1.  </em>

<em>2.  Divide b by 2. </em>

<em>3.  Square (b/2) </em>

<em>4.  Add (b/2)^2 to both sides to keep the polynomial balanced. </em>

<em>5.  You can now write the perfect square trinomial and solve. </em>

<em><u> </u></em>

x^2 - 3x  

-3/2

(-3/2)^2 = 9/4 = 2 1/4

Which shapes can be drawn with two opposite angles equal to 105°
sertanlavr [38]

Answer:

see the explanation

Step-by-step explanation:

we know that

A shape with two opposite angles equal to 105° could be a quadrilateral, a parallelogram, a rhombus or a trapezoid

Because

<em>A quadrilateral</em>: A quadrilateral is a four-sided polygon. The sum of the interior angles in any quadrilateral must be equal to 360 degrees

so

If the quadrilateral have two opposite angles equal to 105°, then the sum of the other two interior angles must be equal to

360^o-2(105^o)=150^o

<em>A parallelogram</em>: A Parallelogram is a flat shape with opposite sides parallel and equal in length. Opposite angles are congruent and consecutive angles are supplementary

so

If the parallelogram have two opposite angles equal to 105°, then the measure of each of the other two congruent interior angles must be equal to

180^o-105^o=75^o

<em>A rhombus</em>: A Rhombus is a flat shape with 4 equal straight sides. A rhombus looks like a diamond. All sides have equal length. Opposite sides are parallel. Opposite angles are congruent and consecutive angles are supplementary

so

If the Rhombus have two opposite angles equal to 105°, then the measure of each of the other two congruent interior angles must be equal to

180^o-105^o=75^o

<em>A trapezoid</em>: A trapezoid is a 4-sided flat shape with straight sides that has a pair of opposite sides parallel

so

If the trapezoid have two opposite angles equal to 105°, then the sum of the other two interior angles must be equal to

360^o-2(105^o)=150^o
