QUESTION 1
The given expression is
The greatest common factor is .
We factor to obtain;
QUESTION 2
The given quadratic equation is
We split the middle term to obtain
Factor by grouping;
Use zero product property;
QUESTION 3
The given system of equation is
If we multiply by 3, we obtain;
If we multiply by 4 we obtain;
Adding the last two equations will give us;
The y-variable is eliminated.
Answer:Multiply 3x+4y=−8
by 3. Multiply 7x−3y=6 by 4. Add the resulting equations together.
the answer is 9.
10+x=13
subtract 10 from both sides.
x=3
since this is one third of the number we need to find,you do reverse operations.
multiply 3 by 3.
the answer is 9.
hope this helped. god bless. :D
The triangle lines of symmetry are 60 degrees apart option (A) 60 degrees is correct.
<h3>What is a regular polygon?</h3>
A polygon is a geometric figure with a finite number of sides in two dimensions. On the sides or edges of a polygon, straight-line segments are joined end to end to form a closed shape. The vertices, also known as corners, are the points where two line segments meet and form an angle.
As we know,
The act of using mathematics to address issues in the actual world is known as mathematical thinking.
As the pentagon has 5 sides and 5 lines of symmetry.
The pentagon's lines of symmetry are apart 72(360/5) degrees apart.
Similarly in the triangle, the sum of the interior angle is 180 degrees
The triangle lines of symmetry are 60(180/3) degrees apart.
Thus, the triangle lines of symmetry are 60 degrees apart option (A) 60 degrees is correct.
