Answer:
Isosceles triangle.
Step-by-step explanation:
On the basis of the lengths of the sides of a triangle, below are three types of triangles.
Equilateral triangle: The triangle in which the lengths of all sides are equal.
Isosceles triangle: The triangle in which the lengths of any two sides are equal.
scalene triangle: The triangle in which the lengths all the three sides are different.
Here, the length of the sides are 24 24 and 4.
Since, two sides are equal in length.
Hence, it is an Isosceles triangle.

Answer
7,0
Step-by-step explanation:
Substitute -6y+7 into problem one where the x is
distribute the 2 and subtract the 9 y and you will get
-21y+14=14
subtract 14 from both sides and it will be -21y=0 so y will be 0
substitute the 0 into equation 2 and find x=7
Answer:
The solutions of the equation x^2-1=-x^2+7 are (-2,3) and (2,3)
