Answer:
A ≈ 2 ft²
Step-by-step explanation:
The area (A) of a triangle using Heron's formula is
A = 
where s is the semiperimeter and a, b , c the sides of the triangle.
s = 
= 
= 
= 4.5
Then
A = 
= 
= 
≈ 1.9843...
= 2 ft² ( to the nearest square foot )
704 ( I'm assuming this is rectangular prism )
Follow this formula:
width x length x height = volume
Base is height x length so half of the problem is solved. Next just multiply that by the width and you found your answer.
If it is exactly 90 degrees you are looking for, your answer would be, 3:0:0. Which is 3:00.
Answer:
Option C.
Step-by-step explanation:
Shortest way to solve this question is to find the factors of the given expression.
The given expression is (x² + 13).
Now we have to factorize it.
(x² + 13) = x² + (√13)²
= x² + [-(i)²√(13)²] [Since i = √(-1)]
= x² - (i√13)²
= (x - i√3)(x + i√3) [Since (a² - b²) = (a + b)(a - b)]
Option C will be the answer.
