Answer:
x = 15
Step-by-step explanation:
Sides opposite congruent angles are congruent:
x + 10 = 2x - 5
15 = x . . . . . . . . . add 5-x
The value of x is 15.
_____
I suppose you could show the intermediate step:
x +10 +(5 -x) = 2x -5 +(5 -x)
15 = x . . . . . simplified
I believe that would be 50 :)
Answer:
x^2 + 8x + 15
Step-by-step explanation:
( x + 3 ) ( x + 5 )
1. distribute
( x + 3 ) ( x + 5 )
x^2 + 3x + 5x + 15
2. simplify
x^2 + 8x + 15
