Step-by-step explanation:
Multiply numerator and denominator by the "conjugate" of the denominator.
__
This is done in different scenarios in order to take advantage of the factoring of the difference of squares. Square root terms and imaginary terms in the denominator can be eliminated in this way.
a² - b² = (a -b)(a +b)
Answer:
75 feet
Step-by-step explanation:
the shadow to the object would be a 4:5 ratio
since the shadow of the flagpole is 60 ft,
4x=60 so x would =15
then you multiply 15 by 5 and end up with 75
For this, all you need to do is factor out the GCF, or greatest common factor. To find the GCF of these terms, list the factors of each term and the greatest one they share is their GCF. In this case, the GCF is 5x. <u>Factor out 5x from this expression, and your answer is going to be 
</u>
The answer is B. 1.5 but I’m not sure bc I can’t see what C. Is
44.6 is the answer, but the estimate is 45 since you round up from .5+
