Answer is B.
5√3(5+2√6)=
25√3+10√18=
25√3+30√2
Note: I multiplied 10 by 3, because the prime factors of 18 are 3, 3 and 2 so I made a pair from the 3 and multipled and was left with 2.
Answer:
5 feet
Step-by-step explanation:
P = 2(w + l)
P = 34
l = w + 7
34 = 2 (w + w + 7)
34 = 2w + 2w + 14
34 - 14 = 4w
20 = 4w
w = 5 feet
Since l = w + 7
l = 5 + 7
l = 12 feet
Step-by-step explanation:
n/6+2=0
n/6+2/1=0
find the LCM=6
n+12/6=0
cross multiply
n+12=0
n=-12
