It is B because I had the question before in my school
Answer:
h = 2
Step-by-step explanation:
I'm assuming your periods are multiplication signs.
(h + h) X (h X h) = 16
When adding two variables like the first set of parentheses, it would become 2h. When multiplying two like variables, you add the exponents. h is the same as writing h¹. So h¹ x h¹ gives you the answer of h².
So now your equation would look like:
2h X h² = 16
As above, when you multiply two like variables you would add the exponents. Also if any number are in front of the variable you would multiply those numbers. So you have 2h¹ x 1h² and that would be 2h³. If it had been
2h¹ x 2h², your answer would have been 4h³.
But so far you have 2h¹ x 1h² = 16
2h³ = 16
Dividing both sides by 2 you get
h³ = 8
To find h you have to take the cubed root of 8. What number multiplied by itself 3 times gives you 8? 2 x 2 x 2 = 8 2 x 2 = 4 and x 2 = 8.
h = 2
If you put this into the original equation you have:
(2 + 2) x ( 2 x 2) = 16
( 4 ) x ( 4 ) = 16

Answer:
14
Step-by-step explanation:
Although the typing has some typographical issues. We could extract the following:
First quartile (Q1 => 0.25) = 4
Second quartile/median (Q2 => 0.50) = 5
Third quartile (Q3 => 0.75) = 10.
The upper fence (maximum):
==>[Q3 + Q1] = 10+4 = 14.
NB: If all our assumed values from the question are correct!
Answer:
Reflexive Property of Equality
