If  68  is a prime number, then the only factors it has are  1  and  68.
If it has any other factors besides  1  and  68, then it's NOT prime.

Right away, without any higher math, you can look at just the last digit
in 68 .  The last digit is '8'.  That tells you that '68' is an even number,
and THAT tells you that '2' must be one of its factors.  So '68' is not a
prime number.

The factors of  68  are  1,  2,  4,  17,  34, and  68 .    

68  has four more factors besides  1  and  68, so it's not a prime number.

Write the expression in the simplest terms (x^2-10)+(10^2+2)
Leto [7]
X^2+92 is the simplest form first solve the second parentheses. 10^2+2=102 then add -10. 102+-10 is the same as 102-10=92 plug back in x^2+92.

7m + -10 =-10 what is m?
tigry1 [53]

Answer:

m = 0

Step-by-step explanation:

Given

7m + -10 = -10

Positive negative gives negative.

So the expression can be rewritten as

7m - 10 = -10

Add 10 to both sides of the equation

7m - 10 + 10 = -10 + 10

7m = 0

Divide both sides by 7

7m /7 = 0/7

m = 0
