Step-by-step explanation:
Let's solve your equation step-by-step.
√a+5=4
Solve Square Root.
√a+5=4
a+5=42(Square both sides)
a+5=16
a+5−5=16−5(Subtract 5 from both sides)
a=11

Answer:
x= 1/3 =0.333
Step-by-step explanation:
Step-by-step explanation:
f(n) = - 29 - f( n - 1 )
f(1) = - 16
Now
f(2) = - 29 - f ( 2 - 1 )
= - 29 - f ( 1)
= -29 - ( - 16)
= - 29 + 16
= - 13

It states that we can add numbers regardless of the groups. The sum does not change irrespective of how the addends are grouped.
We are given the expression:

It can be written as:

It can also be written as:

Whatever maybe the arrangement of r, h and t, their sum will always be equal. We can regroup them in many ways but the sum remains the same.
