Hi there!
The answer is D.
We need to isolate each square root. We can simply do this by adding
to both sides of the equation.
When we isolated the square roots, our equation looks like this:
Now we can easily square both sides of the equation, which would have been much harder earlier.
~ Hope this helps you!
Answer:
1. False
2. False
3. True
Step-by-step explanation:
1. The diagonals of a rectangle always form four congruent triangles, which is a false statement.
The counter-statement will be, the diagonals of a square always form four congruent triangles.
2. A quadrilateral has perpendicular diagonals. Is this enough to determine what type of quadrilateral it is?
The answer is no.
The counter-statement will be, a quadrilateral has perpendicular diagonals, then it may be a rhombus or a square.
3. Explain why drawing a diagonal on any parallelogram will always result in two congruent triangles and it is true that the two triangles will be congruent as the opposite sides of the parallelogram are equal and there is a common side which is the diagonal itself.
Therefore, using SSS criteria the triangles are congruent. (Answer)
Answer:
(x + 5)
Step-by-step explanation:
(x² - 25) ÷ (x-5)
=(x² - 5²) ÷ (x-5)
Using the formula a² - b² = (a + b)(a - b) you get
= (x + 5)(x - 5) ÷ (x - 5)
With division you can cut both (x - 5)
So the answer is (x + 5)
Answer:
c
Step-by-step explanation:
we add them which gets 440. afterwards we don't round since it's a profitable and stable amount
