we are given that
two triangles are similar
so, the ratio of their sides must be same
we get

now, we can solve for x
step-1: Cross multiply both sides

step-2: Simplify left side

step-3: Subtract both sides by 2x


step-4: Divide both sides by 4

so,
............Answer
Last one i think
x=0 or x=6
Answer: x<-16
Step-by-step explanation:
If an object has a density of less than
g/ml, the object will float in water.
So, fourth option is correct

The object with density less than
g/ml will float, and the object with a density more than
g/ml will sink.
So, if an object has a density of less than
g/ml, the object will float in water.
Therefore, fourth option is correct

=(f-g)(x)
=f(x)-g(x)
=x+6-(x-6)
=x+6-x+6
=12
