Answer:
a = 9/2
Step-by-step explanation:
In order for the equation to be true, the value of the scalar multiplier must be ...
15/3 = -10/-2 = 35/7 = 5
So, you're solving ...
(2/3)a + 2 = 5
(2/3)a = 3 . . . . . . subtract 2
a = 9/2 . . . . . . . . multiply by 3/2
4a^2+7ab-b^2
Step-by-step explanation:
Add the first two equations together:
3a^2-ab-2b^2
+ 2a^2+5ab-3b^2
---------------------------
5a^2+4ab-5b^2
Subtract that answer from the remaining trinomial:
5a^2+4ab-5b^2
- a^2-3ab-4b^2
--------------------------
4a^2+7ab-b^2

Answer:
1) Congruent
2) Congruent
3) Not Congruent
4) Congruent
5) Congruent
6) Congruent
Step-by-step explanation:
1) If you laid the triangles in the same direction, they both share the bottom angle and top angle, making it congruent. If you use this same thought process, you can figure out the rest.
[2] \frac{x}{y} [/3]*[1] \frac{x}{y} [/3]=[2] \frac{x}{y} [/9]
2*1=2
