Answer:

-4\sqrt{5}

Step-by-step explanation:

Given expression: (square root 5) - (3 square root 5)

  • ⇒ -\sqrt{5} - 3\sqrt{5}

Since we have √5 common in both terms, let's factor √5.

  • ⇒ \sqrt{5} - 3\sqrt{5}
  • ⇒ \sqrt{5} \times (-1 - 3)

Finally, we can simplify;

  • ⇒ \sqrt{5} \times (-4)
  • ⇒ -4\sqrt{5}

Therefore, the combined radical of (square root 5) - (3 square root 5) is -4\sqrt{5}

Help me please please
Ivan
Answer: 11

============================================

Explanation:

Point C is the circumcenter of triangle PQR. This means that we can draw a circle centered at C that goes through points P, Q and R at the same time. This circle has a special name: circumcircle.

The segments PC, RC and QC are all radii, so they are the same length. Pick two of the given expressions and set them equal to one another. Then solve for x

I'm going to pick the expressions for PC and RC

PC = RC
3x+7 = 5x-15
5x-3x = 7+15
2x = 22
x = 22/2
x = 11

alexandr402 [8]
Well you could multiply 432 by 0.75, or you can divide it by 4 and then multiply it by 3. Either way your answer is 324.

State if the two triangles are congruent. If they are, state how you know.
Gwar [14]

Answer:

The triangles can be congruent.

Step-by-step explanation:

They are congruent if proven by SSS: 2 sides are clearly stated that they are congruent due to the marks they have.

The last side can be congruent if the diagonals are congruent in length by proving.

They can also be congeuent due to SAS because there is gonna be alternate interior angles due to the transversal.
