Answer:
a) 2√3 - 2√2
h) -11√2
Explanation:
You are combining all of the like terms, which are the terms with the same number underneath the radical.
So for this problem, the x-axis is the horizontal line in the center.
Go to where -2 is on the x-axis as shown. Use your finger to trace along since that's usually helpful in finding the point.
Move your finger from -2 on the x-axis to where the solid black line is. On the right side of that, you can see that the y-axis holds the number 2 which is what the y equals for this solid line.
Therefore, the answer should be c.) y = 2

<h3>What is ratio?</h3>
A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Given ratio: A: B : C = 5 : 3 :2
let the common ratio be 'x'.
Grade A cost = 5x
Grade B cost = 3x
Grade C cost = 2x
cheapest seats the concert £16
So,
2x=16
x=8
Now, Grade A cost = 5x = 5*8 = £40
Grade B cost = 3x= 3*8 = £24.
