You need to use the equation for adding fractions, which is

In this case, a=-1, b=3, c=-3, d=5.

simplify
answer:
<h3>
<u>Required</u><u> Answer</u><u>:</u><u>-</u></h3>
This is an right angle ∆ and the side lengths containing a right angle are 9 and 11.
By Pythagoras theoram,

where p is the perpendicular, b is the base and h is the hypotenuse.
Plugging the values,

Then,


<h3>
<u>Hence:</u><u>-</u></h3>
The x of the right angled ∆ = <u>1</u><u>4</u><u>.</u><u>1</u><u>2</u>
Answer:
(i) 520
(ii) 2
Step-by-step explanation:
(i) x³ + y³
Plug x as 2, and y as 8.
(2)³ + (8)³
Solve for exponents.
8 + 512
Add.
= 520
(ii) ∛y
Plug y as 8.
∛(8)
Solve for cube root.
= 2
To find the lowest common denominator between the fractions, what you need to do is simply write out the multiples of both 3 and 5 and find what multiple is common between both:
3,6,9,12,15
5,10,15
The multiple that is common and is the lowest in both would be 15.
The solution thus is B.15, it is the LCD for the fractions of 2/3 and 4/5.
