To solve you multiply 4x5=20 and 3x7=21. The numbers are not equal, so they are not proportional. (Hope this helps!)

Answer:

No they are not proportional.

Step-by-step explanation:

If you make the ratio into a fraction it looks like this

4/7 and 3/5

Now you cross multiply

4*5 and 3*7

Now you have 20 and 21

Those numbers are unequivelent

So they are not proportional

2^2x+2 *5^x-1=8^x*5^2x

Liula [17]

Answer:

The solution will be "x = 2 and x = -1".

Step-by-step explanation:

The given equation is:

⇒ $2^{2x+2}\times 5^{x-1}=8^x\times 5^{2x}$

On solving " $8^x$ ", we get

⇒ $2^{2x+2}\times 5^{x-1}=(2^3)^x\times 5^{2x}$

As we know, if the base are same then their powers will be added together.

⇒ $2x+2=3x$ ...(equation 1)

⇒ $x-1=2x$ ...(equation 2)

From equation 1, we get

⇒ $2=3x-2x$

⇒ $2=x \ i.e., x =2$

From equation 2, we get

⇒ $-1=2x-x$

⇒ $-1=x \ i.e., x=-1$

So that the correct answer will be "x = 2" and "x = -1".
