Answer:
C) 147 ft²
Step-by-step explanation:
Bottom rectangle:
A = bh
A = 14(7)
A = 98
Top rectangle:
A = bh
A = 7(7)
A = 49
Combined:
98 + 49
147
The correct option is (B) yes because all the elements of set R are in set A.

What is an element?</h3>
- In mathematics, an element (or member) of a set is any of the distinct things that belong to that set.
Given sets:
- U = {x | x is a real number}
- A = {x | x is an odd integer}
- R = {x | x = 3, 7, 11, 27}
So,
- A = 1, 3, 5, 7, 9, 11... are the elements of set A.
- R ⊂ A can be understood as R being a subset of A, i.e. all of R's elements can be found in A.
- Because all of the elements of R are odd integers and can be found in A, R ⊂ A is TRUE.
Therefore, the correct option is (B) yes because all the elements of set R are in set A.

The complete question is given below:
Consider the sets below. U = {x | x is a real number} A = {x | x is an odd integer} R = {x | x = 3, 7, 11, 27} Is R ⊂ A?
(A) yes, because all the elements of set A are in set R
(B) yes, because all the elements of set R are in set A
(C) no because each element in set A is not represented in set R
(D) no, because each element in set R is not represented in set A

Step-by-step explanation:
The distance between two points can be found by using the formula
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(-1,-7) and (8,-9)
The distance between them is
We have the final answer as

A=25x^2•16y^4
Answer:
see explanation
Step-by-step explanation:
Using Pythagoras' theorem, that is
The square on the hypotenuse of a right triangle is equal to the sum of the squares on the other two sides.
Using x instead of ?
(a)
The hypotenuse is the side opposite the right angle, that is 74, thus
24² + x² = 74²
576 + x² = 5476 ( subtract 576 from both sides )
x² = 4900 ( take the square root of both sides )
= 
x = 70
----------------------------------------------------------------------
(b)
The hypotenuse x is the unknown side here
x² = 40² + 40² = 1600 + 1600 = 3200
Take the square root of both sides
= 
≈ 56.6 ( nearest tenth )
