Is a triangle with the side lengths 4 feet, 7. 5 feet, and 8. 5 feet a right triangle? Why or why not?

Answers

Answer:

Yes

Step-by-step explanation:

You can test if a triangle is right-angled by using Pythagoras' Theorem.

So:

[tex]4^2 + 7.5^2 = 8.5^2[/tex]

16 + 56.25 = 72.25

They do in fact add up so this triangle is right angled.

The area of a rectangle is (x4 4x3 3x2 – 4x – 4), and the length of the rectangle is (x3 5x2 8x 4). if area = length × width, what is the width of the rectangle? x 1 x – 9 x 4 x – 1

Answers

Answer:

Area = x4 + 4x3 + 3x2 - 4x - 4

Length = x3 +5x2 + 8x + 4

Width = Area / Length.

Performing long division with polynomial.

x4 + 4x3 + 3x2 - 4x - 4 / x3 + 5x2 + 8x + 4 = x-1

Width = x-1

Step-by-step explanation:

The value of the width of the rectangle is,

⇒ (x - 1)

We have to given that;

In a rectangle;

Area = x⁴ + 4x³ + 3x² - 4x - 4

Length = x³ +5x² + 8x + 4

We know that;

Width = Area / Length.

Hence, Performing long division with polynomial.

Width = x⁴ + 4x³ + 3x² - 4x - 4 / x³ +5x² + 8x + 4

= x - 1

Thus, The value of the width of the rectangle is,

⇒ (x - 1)
