2:4 and 5:6 equivalent?

1 answer:

7 0

Well, no, 2:4 and 5:6 are not equivalent because let’s say if we drew 2:4 and 5:6 as a pizza, then 2:4 is 50% while 5:6 is 83%.

5x + 15 = 2x +3<br> x = what

gladu [14]

$5x + 15 = 2x + 3 \\ 5x + 15 + 3 = 2x \\ 5x + 18 = 2x \\ 18 = 2x - 5x \\ - 3x = 18 \\ x = \frac{18}{ - 3} \\ \\ x = - 6$

Hope this will help...

Fine the product mentally. [(x+1) (x-1)^2

Murljashka [212]

If the product is: [(x+1) (x-1)]^2 , the answer is:
[(x+1) (x-1)]^2 = [x^2-1]^2 = x^4-2x^2+1

Please help Asap, will give brainiest only if answer correctly with a good explanation

Bogdan [553]

Answer:

D, or the last option.

Step-by-step explanation:

See how the rotation does not say whether it is Clockwise or Counterclockwise?

Now, what that means, is that it will, default, be CCW. I don't know why, but math teachers are like that.

Now, 80* and 10* add up to 90* (because they are both unmarked and going to the same direction).

So, 90* rotation CCW. Simple! Thus, the last option should be correct.

Hope this helps!

P.S. Stay Safe!
