Answer: The answer is 
Step-by-step explanation: Given that Rei is barricading a door to stop a horde of zombies by satcking boxes of books on a table in front of the door.
The weight of each box is 30 kilograms and the weight of the table with 8 boxes on the top is 310 kilograms.
So, if 'g' denotes the weight of the table alone, then we have

Therefore, the weight of the table without boxes is 70 kilograms.
Now, if 'W' is the total weight of the barricade, then it can be written as a function of 'x', the number of boxes Rei stacks on the table. The expression is as follows -

Thus, the required function is

Answer:
1/2 or 4/8 or 3/6

Answer:
A translation by 3 units to the right and 2 units up
Step-by-step explanation:
(6,4) --> (3,2)
The x-values decrease by 3.
The y-values decrease by 2.
So, x-values are horizontal distances (right/left).
Y-values are vertical distance (up/down).
Our values decreased (left/down)
A translation by 3 units to the left and 2 units down
Answer:
Firstly, we'll apply the below identity.

Applying the above identity.
⇒ (√5 + √2)²
⇒ (√5)² + (√2)² + 2×(√5)×(√2)
⇒ 5 + 2 + 2√10
⇒ 7 + 2√10
Comparing the LHS and RHS
⇒ 7 + 2√10 = a + b√10
∴ a = 7 and b = 2.
