3x + 4y = 17     (1)
-4x - 3y = -18    (2)

multiply equation (1) by 4 and equation (2) by 3 to eliminate x

(× 4)  12x + 16y = 68     (1)
(× 3)  -12x - 9y  = -54     (2)
---------------------------------------------Add
7y = 14
  y = 2

Replace y = 2 into equation (1) 3x + 4y = 17 to find x

3x + 4(2)= 17 
3x + 8 = 17
3x = 9
  x = 3

Find the length of the side of rhoumbus whose diagonals are of length 6cm and 8cm.​
Artist 52 [7]

Answer:

In a rhombus, the diagonals bisect at right angles. That means half the diagonals form a right angle triangle then we can try the Pythagorean theorem. so -

one side of triangle =  6/2 =3 (half of the diagonal)

other side = 8/2 = 4

a^2 + b^2 = c2

3 ^2 + 4^2 = c^2

9+16 = c^2

c^2=25

c = \sqrt{25} = 5

the hypothenus forms one side of the rhombus and here the hypothenus is 5, so the lenght of a side is 5 !

The width of a rectangle is 10 feet shorter than its length. The area of the rectangle is 60 square feet. Find the length and wi
VladimirAG [237]

Answer:

  length: 14.2 ft; width 4.2 ft.

Step-by-step explanation:

Let x represent the length of the rectangle in feet. Then x-10 represents the width, and the area is ...

  area = length×width

  60 = x(x -10) . . . . . substitute the expressions for area, length, width

  60 = x² -10x

  85 = x² -10x +25 . . . . add (10/2)² to complete the square

  85 = (x -5)² . . . . . . . . . rewrite as a square

  √85 = x -5 . . . . . . . . . take the square root. Only the positive root is useful for this problem

  x = 5 + √85 ≈ 14.2

  x-10 = 4.2

The length and width of the rectangle are 14.2 ft and 4.2 ft.
