Answer:
A value that satisfies this equation is called a root, zero or solution of the equation!! We have three ... Solve each by factoring. 1) x2 + 4x -5 = 0 ... Follow the explanation and sample problem to review completing the square.
Step-by-step explanation:
<h3> (8) An aeroplane takes off from Dubai located in the +4 time zone at 13:00. It arrives in Manila in Philippines, located in the +8 time zone at 20:00.</h3>
- (1) Find the time in Manila when the aeroplane departsfrom Dubai.
- (ii) Find the time duration of the flight.
- (iii) What is the time in Dubai when the aeroplane arrives in Manila?
- (i)17.00
- (ii)3 hours
- (iii) 16.00
<h3>Dubai located +4 zone, takes off at 13.00,</h3>
∴Hence, at standard it is 13.00-4 =99.00 STD talk
off reached at Manila +8 Zone at 20.00
∴Hence at standard & 2000 -8
reached.⇒ 12.00 STD
- Hence time of flight was = 3 hours.
(i) Time at Manila, whicle Plane de parts
12-3+8 ⇒9+8 → 17.00
(ii) duration = 3 hours.
(iii) in dubai 13.00 + 3 = 16,00
_____________________
Ans
i)17.0.0 (ii) 3 hours (iii) 16.00

Step-by-step explanation:
The Range (Statistics) The Range is the difference between the lowest and highest values.
The mean is the sum divided by the count.
Answer:
Last year, a small business had a total revenue of $a
This year, this business had a total revenue of $55,200
If this year's total revenue is 15% more than last year's total revenue, the equation expressed the relation between these 2 years' revenue is:
a + 15% of a = 55200
<=> a + (15/100)a = 55200
<=> a x (115/100) = 55200
=> a = 55200 x 100/115 = 48000
=> Last year's revenue: a = 48000$
Hope this helps!

Is this the whole problem????
