The sum of -2 and -7 is given as follows :
-2 + (-7)
In mathematical operations, + * - is - therefore
Now soo we have,

The answer is <em>x</em>=5.
Solve for <em>x</em>. (The question mark should be <em>x</em>.)
(32 ft) x (30 ft + 5/12 ft) = (960 ft² + 13-1/3 ft²) = 973-1/3 feet²
Answer:
the total number of outcome in step 1 = 1+2+3= 6
the total number of outcome in step 2 = 2 +2+3 = 7
hence total number of outcome = 6 x7
= 42
Step-by-step explanation:
A) the integers greater than 10
countable infinite: 1 -> 11; 2 -> 12; 3 -> 13; 4-> 14; 5->15; ...
b) the odd negative integers
countable infinite: 1-> -1; 2-> -3; 3-> -5; 4-> -7; 5-> -9; ...
c) the integers with absolute value less than 1,000,000
finite (-999,999; -999,998; -999,997;...0;...; 999,997;999,998;999,999)
d) the real numbers between 0 and 2
uncountable
e) the set A _ Z+ where A = {2, 3}
finite (it is empty)
f ) the integers that are multiples of 10
countable infinite: 1-> 10; 2-> -10; 3-> 20; 4-> -20; 5-> 30; 6-> -30;...
