It must be odd. As you know, 2 is the only even prime number. Therefore, all prime numbers have the form (2x+1).
For example, two numbers are 2x+1 and 2x+5. We have:
(2x+1)(2x+5)= 4x^2 +12x+5
Since 4x^2+12x is even, 5 is odd, 4x^2+12x+5 must be odd.
Good luck!

Someone help me pls <br><br>47 as the sum of ______
Elanso [62]

9514 1404 393

Answer:

  (a) 6² +3² +1² +1² = 47

  (b) 5² +4² +2² +1² +1² = 47

  (c) 3³ +4² +2² = 47

Step-by-step explanation:

It can work reasonably well to start with the largest square less than the target number, repeating that approach for the remaining differences. When more squares than necessary are asked for, then the first square chosen may need to be the square of a number 1 less than the largest possible.

The approach where a cube is required can work the same way.

(a) floor(√47) = 6; floor(√(47 -6^2)) = 3; floor(√(47 -45)) = 1; floor(√(47-46)) = 1

__

(b) floor(√47 -1) = 5; floor(√(47-25)) = 4; ...

__

(c) floor(∛47) = 3; floor(√(47 -27)) = 4; floor(√(47 -43)) = 2

Of 81 square feet and a base length of 9 feet. What is the height of the parallelogram?
mote1985 [20]
Your answer would be 9 feet
81=area
9=base
_=height
and area is base x hight so you divide the base by the area so an equation would be 81=9x then you would flip it around so it would be 9÷81=x
x=9
Hope this helps!!
