Answer:
x = 0 , x = 5
Step-by-step explanation:
x³ - 10x² + 25x = 0 ← factor out x from each term
x(x² - 10x + 25) = 0 ← (x² - 10x + 25) is a perfect square
x(x - 5)² = 0
Equate each factor to zero and solve for x
x = 0
(x - 5)² = 0
x - 5 = 0
x = 5 ( multiplicity of 2 )
Answer:
D. Opposite angles are congruent
With option A, we can see that it is clearly wrong, in a parallelogram, only the opposite sides are congruent, if all of the sides are congruent then the shape is more likely to be a square or a rhombus.
With option B, only the opposites angles are congruent. If all four angles are congruent, that will be more likely to be true when we consider a square or a rectangle.
With option C, it is also wrong, unless the shape is a rhombus, square or rectangle.
That leaves us with the last option which is D.

Area of a Circle: A = πr²
Step-by-step explanation:
*Note: A semicircle is <em>half</em> a full circle.
<u>Step 1: Define</u>
Radius <em>r</em> = 10 cm
<u>Step 2: Solve for </u><em><u>A</u></em>
- Rewrite Area of Circle Formula: A = 0.5πr²
- Substitute in <em>r</em> [Area of Semicircle Formula]: A = 0.5π(10 cm)²
- [Area] Evaluate exponents: A = 0.5π(100 cm²)
- [Area] Multiply: A = 50π cm²
Answer:
1st and 3rd
Step-by-step explanation:
there are two types of data
they are discrete and continuous
continuous data lines will be just one line while discrete would be dots
the first and third one looking from left to right and up and down would be the right ones
Solving the equation
using completing square method we get 
So, Option A is correct.
Step-by-step explanation:
We need to solve the equation
using completing square method.
Solving using completing square method

For completing the square we need to make formula a^2-2ab+b^2=(a-b)^2
Divide the equations by 2


Adding and subtracting (3)^2 on both sides.



Solving the equation
using completing square method we get 
So, Option A is correct.
