Answer:
13. 4 sqrt(3)
14. sqrt(7)/2
Step-by-step explanation:
13. sqrt(2) * sqrt(3) * sqrt(8)
We know sqrt(a) * sqrt(b) = sqrt(ab)
sqrt(48)
Look for perfect squares
sqrt(16*3)
sqrt(16) sqrt(3)
4 sqrt(3)
14. sqrt(14)/ 2 sqrt(2)
We know sqrt(a) / sqrt(b) = sqrt(a/b)
sqrt(14/2) / 2
sqrt(7)/2
Answer:
-0.4-4y
Step-by-step explanation:
-0.5(0.8+8y)
Distribute -0.5 into the parentheses
= -0.5×0.8+(-0.5)×8y
= -0.4+(-4y)
A negative and a positive make a negative
= -0.4-4y
