Answer:
Step-by-step explanation:
We would multiply the fraction by its conjugate
( A conjugate is a expression that has the same integer or number values but have different signs) for example
and
ARE Conjugates.
The conjugate of
is
So this means we will multiply the expression by 1 plus sqr root of 5 on the numerator and denominator.
Our new numerator will be
We can apply the difference of squares for the denominator.
So our denominator will be
So our rationalized fraction will be
The complete question in the attached figure
we have that
<span>A door to a playhouse is 50 inches tall
we know that
1 in---------------> is 0.0833333 ft
so
50 in-------------> 50*0.0833333---------> 4.167 ft
</span>4.167 ft----------> [4 ft+0.167 ft]
<span>remember that
</span>1 in---------------> is 0.0833333 ft
<span>X in----------------> 0.167 ft
X=0.167/0.0833333----------> X=2 in
therefore
</span>4.167 ft----------> [4 ft+0.167 ft]--------> [4 ft+2 in]<span>
the answer is
the option b) 4 ft 2 in
