Answer:
10 cm
Step-by-step explanation:
The diagonal d divides the rectangle into 2 right triangles with legs 8 and 6 and hypotenuse d
Using Pythagoras' identity in one of the right triangles, then
d² = 8² + 6² = 64 + 36 = 100 ( take square root of both sides )
d = 
= 10 cm
Assume that this number is n.
Difference between two number means the subtraction between them.
Therefore, "<span>The difference between a number and 12 is 20" means that when subtracting these two numbers, the result is 20.
Since the question did not mention which number is greater, therefore, we have two ways to write the equation.
These two ways are as follows:
x - 12 = 20, and
12 - x = 20

Answer:
14/9
Step-by-step explanation:
7/18 + 1/3+ 5/6
1/3 can also be written as 6/18
5/6 can also be written as 15/18
7/18 + 6/18 + 15/8 = 28/18
28/18 can be simplified to 14/9
Hope this helps!
Step-by-step explanation:
7r+18=-2(6-6r)
7r+18= -12+12r
7r = -12-18+12r
-30+12r = 7r
-30 = 7r-12r
-5r = -30
r = 30/5
<em><u>r = 6</u></em>
