Your answer would be the first option: has all sides congruent and all angles congruent.
This is because although this does apply to squares, it can also apply to shapes like a rhombus, as it sits not guarantee that those congruent angles are 90° like they must be for the shape to be a square.
I hope this helps!
If 165 cm is 10% taller, then the equation we can use to find the original age is:
x×1.1=165
This means that to solve for x, we just need to divide by 1.1 on both sides of the equation:
x=150
Therefore, Cody was 150 cm tall last year
We can solve this problem using discriminant.
x^2-4x-12's discriminant is
(-4)^2-4*-12=16+48 which is clearly larger than 0
This means that it crosses over the axes 2 times.
In case you don't know what discriminant is, its in equation ax^2+bx+c
the discriminant is b^2-4ac.
If its positive it has 2 crosses with x axis, if negative then 0 crosses, if 0 then 1 cross.
Hope this helped at least a little bit :D
