Rewrite this expression to simplify it without changing its value what is 1/7 + 1/6 + 3/7

the least common multiple of 7 and 6 is 42, so we can multiply the fractions so the denominator=42.

1/7 + 1/6 + 3/7

= 6/42 + 7/42 + 18/42

now we can add

31/42.

step-by-step explanation:

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
