Answer:
Explanation:
Step 1 - Expand
Step 2 - Combine like terms
Therefore, the expression that is equal to is .
The correct answer is c. First, look at the argument as it is given in writing then convert it too a proof. So, If p and q then, not r. Next the questions is station that not only does p have to be true so does q if not r is to be true also. So, If (p and q) then, not r. Then to finally convert it into a finalized proof as (p∧q)→¬r.
Answer:
Step-by-step explanation:
The picture of the question in the attached figure
we know that
The triangle ABD is an isosceles triangle
because
AB=BD
The segment BM is a perpendicular bisector segment AD
so
<em>In the right triangle ABM</em>
Applying the Pythagorean Theorem
we have
substitute
-----> equation A
<em>In the right triangle BMC</em>
Applying the Pythagorean Theorem
we have
substitute
----> equation B
equate equation A and equation B
solve for x
Simplify
<em>Find the length of DC</em>
substitute the given values
Answer:
a.
Step-by-step explanation:
4<x because the arrow is going to the right, meaning that the value of x is greater and since the circle is hollow, it is not equal to 4 so that's why is
4<x
