SSS
Step-by-step explanation:
The two triangles both share a side (the middle line), and it is shown that the other lines are congruent to each other. So all 3 sides are congruent, meaning SSS is the postulate that proves this.
Answer:
-0.43 > -2.3
Step-by-step explanation:
-2.3 Is further away from zero than -0.43 is. Therefore, -0.43 is larger. (Greater than)
It can't be equal because they are not equal;
And It can't be less than because if you were to add how much it takes to get to zero. it would be 2.3 and 0.43, meaning -0.43 is alot closer to zero (making it the "greatest" value.)
Answer:
-x^2 +12x +5
Step-by-step explanation:
x^2+3x + -2x^2+9x+5
I like to line them vertically
x^2+3x
-2x^2+9x+5
---------------------
-x^2 +12x +5
