Break apart 16x34 into 4 simpler multiplication problems?
if the multiplicity is even, the x-intercept will touch the x-axis and turn away (sometimes people call this "kissing" the x-axis). if the multiplicity is odd, the intercept will go right through the x-axis, so the answer to your question is false. in general, remember that odd crosses and even touches/turns/kisses.
not a clue
well the answer isn't exactly 3 feet, but it's very close at 2.91
first we convert all values to decimals to save time.
to convert a mixed number to a decimal you divide the numerator by the denominator and put the whole number in front of it
now we subtract the original value (7 7/8 or 7.875) from all the cut pieces to find out how much is left.
and there you go.
answer:x = 1000
