Step-by-step explanation:
A fraction is in simplest form when no other factor but 1 will divide into the numerator/ denominator
(1)
← is in simplest form
(2)
← is in simplest form
(3)
( divide numerator/ denominator by 2 )
= 
← in simplest form
Answer:
22
Step-by-step explanation:
just add 8 to 14, then there is your number that would equal 14 if 8 was subtracted from it
We will have to use the formula for the area of a trapezoid on this problem, which is (
and 
are the bases of the trapezoid and 
is the height):
All we need to do is substitute the information we are given into our formula:
Now, let's just simplify the equation:
The missing base has a length of 13 units.
Answer:
Step-by-step explanation:
Find the area of the shape by creating two shapes. A large rectangle and a very small triangle. The area of the rectangle is 13x12, and the area of the triangle is (1/2)3x4. The area of both shapes together is 6+156=<u>162</u>.
Now you can easily calculate the area of each rug and determine whether it is over half of 162 (because 162 is the area of the entire floor), or under half of 162. If it is under 81, then it does not cover at least half of the floor.
12x6 = 72 no
10x9 =90 yes
13x12 = 156 yes
3x12 = 36 no
8x8 = 64 no
