Answer:
AB = 12
Step-by-step explanation:
Since the triangle is isosceles, the sides AB and BC are congruent. Then you have ...
4x = 2x+6
2x = 6 . . . . . . subtract 2x
4x = 12 . . . . . .multiply by 2
The side AB has length 12.

Answer:
Step-by-step explanation:
double distribute
2x^2+3x-10x-15
2x^2-7x-15
First lets write this out:-
?
19 - 10 = 20 - 10
Now lets solve:-
19 - 10 =9
?
9 = 20 - 10
20 - 10 = 10
9 ≠ 10
Since 9 does not equal 10:-
19 - 10 ≠ 20 - 10
