8it is 8 .......................
The last step of an equation whose solutions are x=-10 and x=-5 is:
(x+10)(x+5)=0
We need to add some previous steps, which make the equation an absolute value equation.
A way to do this, is writing |(x+10)(x+5)|=0,
the only solutions are still x=-10 and x=-5
Answer: |(x+10)(x+5)|=0

Answer:
Step-by-step explanation:
If ΔABC ~ ΔDEF
Then their sides must be proportional such that:
=>
Cross Multiplying
=> x * 6 = 8*3
=> 6x = 24
Dividing both sides by 6
=> x = 4
