Well an <span>an </span>irrational number<span> is a real </span>number that cannot be expressed as a ratio of integers, i.e. as a fraction. A rational number<span> is a </span>number<span> that can be written as a ratio. So 3/7 is a rational number, 0.38(with a line saying its continuous over .38) is rational, Square of 7/9 is irrational number, and 5 pi is an irrational number.</span>
First, always draw. You learned to draw in kindergarben (Yes I spelled it like that on purpose LOL) for a reason.
1) Draw your rectangle on a piece of paper or paint.
2) Scale factor each side to enlarge which means you're going to multiply.
--- Note if it said 'to reduce' then you would divide.
3) Then find the area by multiplying the two given sides (12 x 6 = 72).
4) Don't forget your unit of measurement - 72ft²
So your answer is D.
Answer:
-6
Step-by-step explanation:

input the numbers

do the problem in the parentheses first
-6-12 = -18
now it becomes

simplify and you'll get
-6
this is because -18 ÷ 3 =
-6
7+z / 2
z = 10
replace the value of z
7 +10 /2
use order of operations ( division comes before addition)
7+5 = 12
