______
The right answer is Option B.
Step-by-step explanation:
Given expression is;
5x√2 - 3√2 + x√2
We can add or subtract square roots only when the values inside the square root are same and the variables are also same.
In the given expression, variable x is same with √2, therefore, adding both the roots
6x√2 - 3√2 is equivalent to 5x√2 - 3√2 + x√2.
The right answer is Option B.

Answer:
k = 1/2
y = -108
Step-by-step explanation:
y varies jointly as x and the cube of z
y =kxz^3
We know y=16 when x=4 and z=2 so we can determine k
16 = k (4) 2^3
16 = k*4*8
16 = 32k
Divide each side by 32
16/32 = 32k/32
1/2 = k
y = 1/2 xz^3
Now y=? when x=-8 and z=-3
y = 1/2 * 8 (-3)^3
y = (1/2) *8 (-27)
y =4 (-27)
y = -108
