Answer:
41 sqrt(3)
Step-by-step explanation:
7 sqrt(27) + 5 sqrt(48)
7 sqrt(9*3) + 5 sqrt(16*3)
We know that sqrt(ab) = sqrt(a) * sqrt(b)
7 sqrt(9)sqrt(3) + 5sqrt(16) sqrt(3)
7 * 3 sqrt(3) + 5 *4 sqrt(3)
21 sqrt(3) + 20 sqrt(3)
41 sqrt(3)
Answer:
= -1 1/5
Step-by-step explanation:
-3 3/5 ÷ 3
change -3 3/5 into an improper fraction
-3 3/5 = - (5*3+3) /5 = -18/5
-18/5 ÷ 3
copy dot flip
-18/5 * 1/3
rewrite to make the math simple
-18/3 * 1/5
-6 * 1/5
-6/5
now change this back to a mixed number
5 goes into 6 once with 1 left over
=-1 1/5
