Multiply both numbers to find what the area is....
We want to get out x's together on the right side of the inequality.
So, subtract <em>x </em>from both sides to get 9 < 3x.
Now divide both sides by 3 and we get 3 < x.
I personally like to have my variables on the left so we can move the 3 to the left and the <em>x</em> to the right but if we do that, we have to switch the inequality sign.
So we can rewrite this as x > 3.
Answer:
you need to add more
Step-by-step explanation:
Answer: It's kinda simple, 2/5 and 4/5
Just add 1 to the numerator of the original fraction, and there's where you get 4/5. Then subtract 1 from the original fraction, and that's where you get 2/5!
Answer:
AC is perpendicular to BD
Step-by-step explanation:
Given a triangle ABD. C is the mid point of BD.
To prove that the two triangles are congruent we have to use SAS axiom.
Here consider two triangles ABC and ADC
Statement Reason
1) BC = CD D is the mid point of BD
2) AC = AC Reflexive property
Since we have two sides congruence we must have included angle congruence
i.e. Angle ACB = Angle ACD
If this information is given, then this completes the SAS congruence for the two triangles ABC and ADC
Hence answer is
the information that AC is perpendicular to BD is sufficient to complete the proof.
