The sum of two integers is 9 and the sum of their squares is 53. Find the integers.
Schach [20]
X + y = 9 Subtract x from both sides.
y = 9 - x

x^2 + y^2 = 53
x^2 + (9 - x)^2 = 53 Remove the brackets.
x^2 + 81 - 18x + x^2 = 53 Collect the like terms on the left.
2x^2 - 18x + 81 = 53 Subtract 53 from both sides.
2x^2 - 18x + 81 - 53 = 0
2x^2 - 18x + 28 = 0 This factors, but you can see it much easier if you pull out 2 as a common factor.
2(x^2 - 9x + 14) = 0
2(x - 2)(x - 7) =0 You could divide by 2 on both sides. But you can also leave it.
x - 2 = 0
x =  2
x - 7 = 0
x = 7
If x = 2 then y = 7
If x = 7 then y = 2

Is a triangle with the given side lengths of 15cm, 17cm, and 19cm a right triangle?
Alexandra [31]
Lets see!
We need to use the pythagorean theorem (a^2+b^2=c^2) to check.
So..
15^2+ 17^2 = 19^2
225+ 289= 361
Hm 225 and 289 do NOT equal 361 therefore it is NOT a right triangle.

5/3(6x+3)<2x-7 what is the solution for the iniquality
leva [86]
Isolate "x" onto one side:

5/3 * (6x+3) < 2x - 7

5(6x+3) < 3(2x-7)

30x + 15 < 6x - 21

24x < -36

x < -1.5

Need help anyone who can help plz
olasank [31]

Answer:

A) x=40°

B) They have the same lengths.

Step-by-step explanation:

Since it is an isosceles triangle, both sides are the same. So if you add up all the angles of any triangle, it should always add up to 180°. There is a 50° angle and a right angle (90°) so you subtract 50 and 90 from 180 (180-50-90) and you get 40. X has to be 40° :)
