Answer:

\small{\boxed{\tt{2 \sqrt{5} (13 +  \sqrt{2}  = 26 \sqrt{5}  + 2 \sqrt{10}  = 64.3}}}

Step-by-step explanation:

Given : Expression

2  \sqrt{5} (13 +  \sqrt{2} )

To find : Simplify the expression

Solution :

Step 1 - Write the expression

2 \sqrt{5} (13 +  \sqrt{2} )

Step 2 - Apply distributive property,

a(b + c) = a × b + a \times  c

= 2 \sqrt{5}  \times 13 + 2 \sqrt{5 }  \times  \sqrt{2}

Step 3 - Apply square root property,

\sqrt{x}  \times  \sqrt{y}  =  \sqrt{xy}

= 26 \sqrt{5}  + 2 \sqrt{10}

or to simplify more substitute the value of \sqrt{5}  = 2.23 and \sqrt{10}  = 3.16

Simplification-

= 26(2.23) + 2(3.16)

= 57.98  +  6.32

<h3>= 64.3</h3>

Questions 7-12<br> Plzzz respond ASAP
Sedaia [141]

Answer:

7-10. domain is all x, range is all y

11. just name all numbers other than 6, 8, and 10 (1, 2, 7, etc.)

12a. (-1,0), (-2,-1), (0,1) (1,2)

12b. Yes, none of the domains are the same and the ordered pairs listed above all follow the rules stated. If it did not follow the rules, the pair(s) would not be Relation B

Step-by-step explanation:

11: In order for relations to be functions, the "x" of the pair needs to be different from the rest. Having the same "x" as another ordered pair would not make it a function.

12a. Follow the rules they state, x ==> y (which I think means x is the number before y) and y > x, honestly not even sure if this is correct

12b. If x ==> was correct in my interpretation, then the ordered pairs I listed should all fit within the boundaries of what relation B would be defined as.
