Answer:
C
Step-by-step explanation:
As we can see, there are perfect squares in the first two expressions
thus, we have it that;
√(25x) = 5√x
√(4x) = 2√x
so we have the expression as;
5 √x - 2 √(x + 2 √x
= 5√x
Answer:
the answer is A 579m/s
Step-by-step explanation:
Given,
v=? u=3m/s a=4m/s^2 and t=72
Now,
v=u+2at
=3+2{4(72)}
= 3+2(288)
=3+576
=579m/s
