A. Yes, since a square is a type of rectangle, but it has four congruent and parallel side.
B. Yes, since a square is also a type of parallelogram. Therefore it has 2 pairs of parallel sides.
C. No, they have 2 pairs of congruent sides.
Hope this helps :D

Part A: Yes, because a square is both a rectangle and a rhombus so therefore it is.
Part B:Yes, Because square falls under parallelogram and a parallelogram has 2 parallel sides.

Applying the Pythagorean theorem, the missing lengths in the right triangles are:

1. √19 ≈ 4.4

2. √96 ≈ 9.8

3. √60 ≈ 7.7

4. √231 ≈ 15.2

5. √21 ≈ 4.6

6. √24 ≈ 4.9

<h3>What is the Pythagorean Theorem?</h3>

The Pythagorean theorem is a formula that can be used to find the leg of a  right triangle, and is given as: c² = a² + b², where a and b are the smaller legs and c is the longest leg/hypotenuse.

1. missing leg = √(10² - 9²) = √19 ≈ 4.4

2. missing leg = √(11² - 5²) = √96 ≈ 9.8

3. missing leg = √(8² - 2²) = √60 ≈ 7.7

4. missing leg = √(16² - 5²) = √231 ≈ 15.2

5. missing leg = √(5² - 2²) = √21 ≈ 4.6

6. missing leg = √(7² - 5²) = √24 ≈ 4.9

Evaluate this piecewise function
ohaa [14]

Answer:

f(-2) = 2 and f(0) = 0.

Step-by-step explanation:

The piece wise function is given by, f(x) = x³ for x ≠ - 2 and f(x) = |x| for x = - 2.

Now, as defined above at x = -2, f(x) = |- 2| = 2

So, f(-2) = 2

Again, at x = 0, f(x) = x³ = (0)³ = 0.

So, f(0) = 0.

Hence, f(-2) = 2 and f(0) = 0. (Answer)

What are the coordinates of the vertex of the graph of y = x2 + 8x + 1?
Rus_ich [418]

Answer:

y= x2 + 8x - 1 is y=(x+4) 2-17

Step-by-step explanation:

First find  - b/2 = - 4, so  -4 will be added to x inside the parenthesis.

Next , find c - b2 to find the value you added at the end

y= (x- b2) 2 + c - b2

y= (x+4) 2 - 17
