Answer:
358
Step-by-step explanation:
9 times 4 equals 36 times 2 equals 72
11 times 4 equals 44 times 2 equals 88
9 times 11 equals 99 times 2 equals 198
198 plus 72 plus 88 equals 358
Answer:
x = 1 y = 2
Step-by-step explanation:
you add the equations and get 3x equals 3 divide x by 3 get 1 x equals 1 substitute x in the first equation for 1 1 plus y equals three subtract one and y equals 2
Hello sir!
It seems as if this is a statement? Seemingly this is David Hilbert's mathematical problem that has yet to be solved.
"The Riemann hypothesis implies results about the distribution of prime numbers. Along with suitable generalizations, some mathematicians consider it the most important unresolved problem in pure mathematics (Bombieri 2000). The Riemann hypothesis, along with Goldbach's conjecture, is part of Hilbert's eighth problem in David Hilbert's list of 23 unsolved problems; it is also one of the Clay Mathematics Institute's Millennium Prize Problems."
Hope this helps! :)
Answer:
445 dollars
Step-by-step explanation:
You are given he charges 47.5 per hour so 47.5x is how much you will pay for x hours and he charges a 65 dollar service fee.
So together he is charge you 47.5x+65 for x hours.
If it spends 8 hours, the cost will be 47.5(8)+65=445.
Use the difference of squares factorization - that for any numbers a and b, (a-b)(a+b)=a^2-b^2.
We have:
(x^2+1)(x^2-1)=x^4-1
In addition:
(x-1)(x+1)=x^2-1, so we have:
(x^2+1)(x+1)(x-1)
As our complete factorization.
