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)]-by-
Answer:
3.52x
Step-by-step explanation:
Let
Quantity of tickets=4
Price of tickets=x
Discount=12%
This means, you will pay 100% -12%
=88%
Total amount payable=discount (quantity * price)
= 88% ( 4 * x )
= 0.88 (4x)
= 3.52x
Answer:
11.2 feet
Step-by-step explanation:
Given: Height of platform (Opposite)= 5 foot
Distance of slope from the base of platform (adjacent)= 10 feet
Picture drawn to show the measurement.
Lets find the length of slope.
Using the Pythagorean theoram.

Subtituting the value in the formula.

⇒ 
⇒ 
Putting square root on both side
We know, √a²= a
⇒ 
∴ hypotenous= 11.18 
Hence, the slope is 11.2 feet
