Answer: x = 7, x = -15
Step-by-step explanation:
This is an absolute value equation, so it has to be simplified first
|x+4|+10=21
|x+4|=11
Then you set it equal to the two values it can be, getting rid of the absolute value sign.
x+4=11
x+4=-11
x = 7
x = -15
Voila!
<em>a²-2ab+b²=</em><em>(a-b)²</em>
x²-10x+5=x²-2×5×x+5²=(x-5)²=(x-5)(x-5)
B.(x-5)(x-5)
Answer: is A i know this because i just took the test.
