The answer is A, because the constant rate has to be the same
The boundary line should be solid because it have a 'great/less than or equal to' sign
Answer:
16 - 40u - 8v
Step-by-step explanation:
(- 2 + 5u + v)(- 8) ← multiply each term in the parenthesis by - 8
= 16 - 40u - 8v
Answer:
10cm
Step-by-step explanation:
First let's define variables a and x:
a = area of rectangle and square
x = side of square
Now let's create an equation to calculate a using the square and an equation to calculate a using the rectangle:
Using square: 
Using rectangle: 
Now we want to solve for x so let's combine the equations since they are both equivalent to a

Simplify

Solving this we get 10 and -3
Since it is impossible for a square to have a negative side value we can conclude that the value is 10cm
This can then be checked by plugging in 10 as x in our equations and seeing if we get the same a value:
Using square: 
Using rectangle:
