The triangle that the height makes would be a 45-45-90 special right triangle. So the height is 3√2, and to find the area, it would be the average of the bases, 7, multiplied by 3√2. So the area of the trapezoid is 21√2.

Answer:
and 
Step-by-step explanation:
An algebraic expression is a polynomial if and only if the variables involve have positive integral indices or exponents.
The given polynomial is: 
We want to put one of the following polynomials in the blank space to create a fully simplified polynomial written in standard form.
A fully simplified polynomial written in standard form is obtained by writing the simplified polynomial in decreasing order according to degree.
Since the first term of having a degree of 5 and the last term is having a degree of 3.
The polynomial that goes into the blank must have a degree of 4.
This eliminates ,
and
We are now left with and
The required polynomial is therefore 
or
These two polynomials are in standard form and cannot be simplified further.
The correct choices are;
and
Well this i need to search which i think i have this page but hold on
Take into account yards to feet conversion. One yard is equal to 3 feet. Convert your yards to feet by multiplying each measurement by 3. [2 x 3 = 6] and [3 x 3 = 9]. Your new area would be 6ft by 9ft. Each tile is 1ft by 1ft. To find the answer you'd simply take your sides and multiply. [6 x 9 = 54]. The answer is 54 tiles.
Answer: The probability of the pointer lands on red(R) both spin =
Step-by-step: The number of parts = 6
The pointer is spun twice.
To find the probability of the pointer lands on red(R) both spin.
Formula
Probability of an event = number of required outcomes ÷ the total number of outcomes.
P(A and B) = P(A)×P(B)
Now,
For one spin,
A = RED comes.
For second spin,
B = RED comes
So,
P(A) = and P(B) =
Then,
P(A and B) = × =
Hence, the probability of the pointer lands on red(R) both spin =
