Answer:

Isosceles Triangle      

Step-by-step explanation:

  • Reflection symmetry exists when the figure can be folded over onto itself along a line. This line is called the line of symmetry.
  • In a regular polygon, the number of lines of symmetry is equal to the number of sides in the polygon.
  • Isosceles triangle is a type of triangle that will always have exactly 1-fold reflection symmetry.
  • 1-fold reflection symmetry means that one line or 1 division can divide the whole figure into two symmetrical parts.
  • An isosceles triangle is a triangle that has two sides of equal length. Isosceles triangle has at least one line of symmetry.

Thus, the answer is Option c) Isosceles triangle.

What is the solution set of the equation x ^ 2 - 3x - 10 = 0 ? pls show work
Yanka [14]

Answer:

Factors :- (x - 5) (x + 2)

Values :- x = 5, x = -2

Step-by-step explanation:

= > x^2 - 3x - 10 = 0

= > x^2 - (5 - 2)x - 10 = 0

= > x^2 - 5x + 2x - 10 = 0

= > x (x - 5) + 2 (x - 5) = 0

= > (x + 2) ( x - 5) = 0...factors

= > x = 5, - 2...values

What is another way to write to 72- (-25) ?
Valentin [98]

Your answer would be 1, or 72+25.

What is happening in this case is a negative number is being subtracted from a positive. This means you are taking away a negative. The two negatives cancel each other out, and then it becomes you are adding a positive.

Another way I like to think about this is the two minus symbols combine together to form a plus sign.

Hope this helped!
