A^2 + b^2 = c^2
297^2 + 394^2 = C^2
88209+155236=243445
take the square root of 243445
you get 493.4
which in your answer they're rounded
so your answer is
C. 493
Answer:
-20.2m -11.8
Step-by-step explanation:
(2y + 14.6m + 3.8) – (34.8m + 15.6 + 2y)
Distribute the minus sign
(2y + 14.6m + 3.8) – 34.8m - 15.6 - 2y
I like to line them up vertically
2y + 14.6m + 3.8
– 2y -34.8m - 15.6
------------------------------
-20.2m -11.8
The square of an odd number:
We're to conjecture, not do algebra, apparently. 1²=1, 3²=9, 5²=25, 7²=49, ...
We conjecture the square of an odd number is odd.
The product of two evens and an odd:
Again, we'll run some examples.
(2)(2)(1)=4
(2)(4)(3)=24
(4)(6)(5) =120
(4)(8)(1)=32
Conjecture: The product of two evens and an odd is a multiple of 4
Counterexample: The product of two fractions is never an integer
How about
3/4 × 4/3 = 1
<span>We want to show that f(g(x)) = x and g(f(x)) = x.
So to do that, we need to calculate f(g(x)) and g(f(x)) explicitly.
Let's begin with f(g(x))
Now, f(g(x)) = f(4/x), by definition of g, as g(x) = 4/x
What then is f(4/x) equal to? Use the definition of f.</span>
