Answer:
x²+1 is the second
Step-by-step explanation:
2x+24=40°
4x+43=75°
x²+1=65°
(2x+24) + (4x +43) + (x²+1)=180
x²+6x+68=180
x1=-14
x2=8
since there's no negative angle, we'll use x=8
 
        
             
        
        
        
Answer:
The options as included in the attachment section are:
A. real numbers B.Cardinality C.element D.Set
The answer is D. Set
Step-by-step explanation:
In mathematics, a set is a group of well-defined objects that share common characteristics as rightly stated in this question. So in a mathematical calculation, the elements or objects collected as a group is called SET. The types of set include empty set, finite set, infinite set, universal set etc. 
- Since set represents the whole collection or group, each object, which can be number, letter etc. in the group is an ELEMENT. Likewise, the cardinality of a set refers to the number of elements contained in a particular set. 
 
        
             
        
        
        
Using Distributive Property, the product of 6x13 is 78.
<h3>
What is Distributive property?</h3>
The distributive property states that multiplying the sum of two or more addends by a number yields the same outcome as multiplying each addend separately by the number and combining the resulting products.
The steps of distributive property are - 
                                                  6 × 13
                                               6 × (10 + 3)
                                           (6 × 10) + (6 × 3)
                                   ((3 + 3) × (5 +5)) + ((3 + 3) × 3)
                  (3 × 5 + 3 × 5 + 3 × 5 + 3 × 5 ) + ((3 × 3) + (3 × 3))
                                      (15 + 15 +15 + 15 ) + (9 + 9)
                                                   60 + 18
                                                     = 78
