Answer:

x = 20

Step-by-step explanation:

Write and solve an equation of ratios, as follows:

  1 3/4         14

------------ = --------

  2 1/2           x

where x is the unknown number.

Converting the mixed numbers to improper fractions, we get:

7/4       14

------ = -----

5/2        x

Here there are two numerators and two denominators.  Multiplying all four quantities by 4 will remove some of the fractions:

 7        56

------ = -------

 10       4x

Cross multiplying, we get:

28 x = 560, or x = 20

the combined area of two squares is 45 square centimetres each side is twice as long as a side of the other square what length o
Ostrovityanka [42]

Answer:

Let the side of  one square be x.    Area = x*x = x²

Then the side of other square  would be 2x ,   Area = 2x*2x = 4x²

Combined area = x² + 4x²  = 5x²

This combined area = 45 cm²

you simplify

Therefore  5x²  = 45   Divide both sides by 5

                 x²  =  45/5

                 x²  = 9        Take square root of both sides

                 x   =  √9

                 x  = 3

Length of larger square is 2x  = 2*3 = 6 cm

Length of larger square = 6cm
