<span>Julia is X+5
</span><span>x+x+5=31
</span>
Now we just solve the equation
2x=31-5
x=26/2
x=13 years old (Babs' age)
and we know that julia is 5 years older this gives us the conclusion that.
13+18=31
Answer:
None of the expression are equivalent to
Step-by-step explanation:
Given
Required
Find its equivalents
We start by expanding the given expression
Expand 49
Using laws of indices:
This implies that; each of the following options A,B and C must be equivalent to or alternatively,
A.
Using law of indices which states;
Applying this law to the numerator; we have
Expand expression in bracket
Also; Using law of indices which states;
becomes
This is not equivalent to
B.
Expand numerator
Using law of indices which states;
Applying this law to the numerator; we have
Also; Using law of indices which states;
=
This is also not equivalent to
C.
Using law of indices which states;
This is also not equivalent to
