Divide 29 into two parts so that the sum of the squares of the parts is 425. Find the value of each part. The sum of the squares of two consecutive natural numbers is 313. Find the numbers.
5 A piece of cloth costs Birr 200. If the piece was 5 m longer, and the cost of each metre of cloth was Birr 2 less, the cost of the piece would have remained unchanged. How long is the piece and what is its original price per metre?
Birr 6,500 were divided equally among a certain number of persons. Had there been 15 more persons, each would have got Birr 30 less. Find the original number of persons
A person on tour has Birr 360 for his daily expenses. If he extends his tour for 4 days, he has to cut down his daily expense by Birr 3. Find the original duration of heil the tour
In a flight of 600 km, an aircraft was slowed down due to bad weather. Its average speed for the trip was reduced to 200 km/hr and the time increased by 30 minutes. Find the duration of the flight.

13 and 16.

Step-by-step explanation:

Let the 2 parts be x and y, then:

x + y = 29

x^2 + y^2 = 425

From the first equation y = 29 - x so substituting in second equation, we get:

x^2 + (29 - x)^2 = 425

x^2 + 841 - 58x + x^2 - 425 = 0

2x^2 - 58x + 416

x^2 - 29x + 208 = 0

208 = 2*2*2*2*13

= 16 * 13

So factoring we get:

(x - 13)(x - 16) = 0

x = 13 ,16

So the numbers are 13 and 16.

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.

well the answer to that is xoxoxo
