Yes, because 24^2 is 576 and 10^2 is 100. Together, its 676. And the square root of 26 is 676. So, yes it is a right triangle.
Answer:
Step-by-step explanation:
19 - you would divide number of beads by beads per bracelet to get number of bracelets
blue = 258/6 = 43
silver = 428/9 = 47.56, round down because we're looking at complete bracelets = 47
rose = 102/3 = 34
white = 258/7 =36.86, round down again = 36
20 - they can make 43 + 47 + 34 + 36 = 160 bracelets before they run out, and they will run out of rose first since it has the smallest number of bracelets
21 - multiply num of beads by num of bracelets for each color and add them up
blue = 6 * 7 = 42
silver = 9 * 7 = 63
rose = 3 * 7 = 21
white = 7 * 7 = 49
42 + 63 + 21 + 49 = 175
Split the second term in 3m^2 + 5 - 8m into two terms
3m^2 - 3m - 5m + 5
Factor out the common terms in the first two terms, then in the last two terms.
3m(m - 1) - 5(m - 1)
Factor out the common term m - 1
<u>(m - 1)(3m - 5)</u>
