Answer:
y varies as √(x+5)
Step-by-step explanation:
y varies as √(x+5)
y= k√(x+5)
k is a constant connecting the two sides.
therefore
k=y/√(x+5)
k=4/√(-1+5)
k= 4/√4
k=4/2
k=2
Y when x=11
y=k√(x+5)
y=2√(11+5)
y=2√16
y=2*4
y=8
Answer:
B
Step-by-step explanation:
Answer:
0.6
Step-by-step explanation:
-4.5-5.1=0.6
If you want to multiply (2*x + 5) and (2*x - 5), you can do this using the following steps:
(2*x + 5) * (2*x - 5) = 4*x^2 - 10*x + 10*x - 25 = 4*x^2 - 25
The correct result is 4*x^2 - 25.
B. End of the reconstruction.
