Answer and Step-by-step explanation:

When two triangles are congruent they will have exactly the same three sides and exactly the same three angles. The equal sides and angles may not be in the same position (if there is a turn or a flip), but they are there.

Now let's solve by using this statement..

1. Yes they are, cause they have excatly the same three sides and excatly the same three angles.

2. no they are not, cause they do not have excatly the same three sides and excatly the same three angles.

3. Yes they are, cause they have excatly the same three sides and excatly the same three angles.

4. Yes they are, cause they have excatly the same three sides and excatly the same three angles.

5. Yes they are, cause they have excatly the same three sides and excatly the same three angles.

6. Yes they are, cause they have excatly the same three sides and excatly the same three angles.

Hope this helped... If yes plz mark as BRAINLIEST and follow me.

X² - 6x + y² + 2y = -1<br> find center & Radius

Fofino [41]

Answer:

The answer to your question is Center = (3 , -1), radius = 3

Step-by-step explanation:

Equation

x² - 6x + y² + 2y = -1

-Process

1.- Leave a space between the like terms

x² - 6x + y² + 2y = -1

2.- Divide the middle term of each group by 2 and write the result to the power of 2 in both sides of the equation.

x² - 6x + (3)² + y² + 2y + (1)² = -1 + 3² + 1²

3.- Simplification

x² - 6x + 9 + y² + 2y + 1 = -1 + 9 + 1

4.- Factor

(x - 3)² + (y + 1)² = 9

5.- Find the center and the radius

Center = (3 , -1)

Radius = √9 = 3

What is the solution to x = square root 3x + 10?

sdas [7]

Answer:

x = 5

Step-by-step explanation:

Given

x = $\sqrt{3x+10}$ ( square both sides )

x² = 3x + 10 ( subtract 3x + 10 from both sides )

x² - 3x - 10 = 0 ← in standard form

(x - 5)(x + 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 5 = 0 ⇒ x = 5

x + 2 = 0 ⇒ x = - 2

As a check

Substitute these values into the equation and if both sides are equal then they are solutions.

x = 5

right side = $\sqrt{15+10}$ = $\sqrt{25}$ = 5 = left side ← solution

x = - 2

right side = $\sqrt{-6+10}$ = $\sqrt{4}$ = 2 ≠ - 2 ← not a solution

Thus x = 5 is the solution to the equation
