Yes they are similar in size because if you simplify both of them to get an equivalent number, 6 x 8 is 3 x 4 simplified and 9 x 12 simplified is 3 x 4. Obviously there are more methods, although I highly recommend this

Basically the question is asking if the proportions for the dimensions of the 2 rugs are the same, so in this case yes, since 6 X 8 can be written as 3 X 4 which if you set up a fraction you can easily multiply both the top and bottom number by 3 to get 9 X 12.

QF Q6.) Find the function for b.
Dimas [21]
The function notation f(x)=2x-4 means replace the x on the right-hand side with the value in parentheses on the left.
For example, f(y)=2y-4; f(4)=2(4)-4=4; f(1)=2(1)-4=-2 and so on.
The same principle applies to g(x), for example
g(2)=4(2^2)-3=13,
g(x+1)=4(x+1)^2-3=4(x^2+2x+1)-3=4x^2+8x+4-3=4x^2+8x+1
and so on.

(g of f)(x) is another way to write g(f(x)), therefore
g(f(x))
=g(2x-4)   [because f(x)=2x-4
=4(2x-4)^2-3
=4(4x^2-16x+16)-3
=16x^2-64x+64-3
=16x^2-64x+61

Find an equation of variation in which y varies directly as x and y = 12 when x = 6
Margarita [4]
Direct variation:-

y = kx where k is a constant

y=12 when x=6 so we have:-

12 = k*6

k = 12/6 = 2

so our equation of variation is  y = 2x Answer
