Answer:
(√2)x/2 or (√2/2)x
Step-by-step explanation:
Let's draw two squares, one with diagonal length x and the other with diagonal length √2. In the second case, the side length is 1, which you can confirm by recalling that 1^2 + 1^2 = 2*1^2 and √2*1^2 = √2.
These two squares are similar, even if they're of different sizes.
Writing an equation of ratios, we get:
side length 1
---------------------- = -------------
x √2
Then (side length)*√2 = x (after cross-multiplication)
and so (side length) = x/√2 or (√2)x/2 or (√2/2)x
Answer:
x=0
Step-by-step explanation:
Take the logarithm of both sides of the equation to remove the variable from the exponent. Hope this helps!
True, because dot plots usually look like this
0 0
0 0 0 0 0

1 2 3 4 5
As you can see, the dots are above the line.
Multiply both sides by 6:
6M = uh
Then divide both sides by h:
u = (6M)/h
Put 3 where x is, then do the arithmetic.
... 3 - 7·3 + 2·3
... = 3 - 21 + 6
... = -18 + 6
... = -12
_____
If you like, you can simplify first.
... = 3 + x(-7 +2)
... = 3 -5x
For x=3, this is
... = 3 -5·3
... = 3 -15
... = -12
