Answer:

f(x)=14

Step-by-step explanation:

First, you simply plug in x=2 into f(x)=7x

Therefore you are left with f(x)=7(2)

Then you must notice that parenthesis mean multiplication...

And.. 7 x 2 =14

Hence your answer of f(x)=14

ABCD is a rectangle ,its diagonals meet at O.If AO = 5x+1 and BO = 4x+9,find the length of the diagonals .(lengths in cm).
Sergeu [11.5K]

Answer:

82 cm

Step-by-step explanation:

In rectangles diagonals are equal and bisect each other

AO = BO

5x + 1 = 4x + 9

Subtract 1 from  both sides

5x  = 4x + 9 -1

5x = 4x + 8

Subtract 4x from both the sides

5x - 4x = 8

x = 8

AO = 5x + 1

     = 5*8  +1

     = 40 + 1

AO= 41 cm

Diagonal = 2*41 = 82 cm
