Answer:
I kind of dont understand the question but it seems like your saying multiply 4.15 x 5 and that is 20.75.
Step-by-step explanation:
Answer:
1. Assume the contrary, namely that √2 + √3 + √5 = r, where r is a rational number.
Square the equality √2 + √3 = r − √5 to obtain 5 + 2
√6 = r2 + 5 − 2r
√5. It follows
that 2√6 + 2r
√5 is itself rational. Squaring again, we find that 24 + 20r2 + 8r
√30
is rational, and hence √30 is rational, too. Pythagoras’ method for proving that √2 is
irrational can now be applied to show that this is not true. Write √30 = m
n in lowest
terms; then transform this into m2 = 30n2. It follows that m is divisible by 2 and because
2( m
2 )2 = 15n2 it follows that n is divisible by 2 as well. So the fraction was not in lowest
terms, a contradiction. We conclude that the initial assumption was false, and therefore
√2 + √3 + √5 is irrational.

Answer:
Step-by-step explanation:
1 inch = 42 miles
3.375 inches = 141.75
since we know that 1 inch = 42 miles. multiply 3.375 to 42 miles and your answer is 141.75 miles. rounding would be 141 or 142.
