Answer:
#2) is 25
Step-by-step explanation:
the best way to solve any of theses is in the order of pemdas:
●parentheses
●exponents
●multiplication & division
●addition & subtraction
for example lets do #2
9+ (2^2)(4)
the first parenthesis has exponents so you'd do it first. 2^2 (two two times) is 4
9+(4)(4)
when two parentheses are next to Each other you multiply. 4x4 is 16
9+16
then finally you add
25
use these steps for the rest. just comment if you have any questions
You should divide each side by 32. Then when you divide the 160 from 32 you should get 5. Because 32x5 =160
All together it equals (of the number of hours he does in a week)
45 because 6 plus 9 is 15 and 15 multipled by 3 is 45 makes sense becuase .. 6 +3 is 9 and 9 +9 is 18 2 weeks equals 14 days 18 subtracted by 14 equals 2 which 45 subtracted by 2 is 43 and that's the esact number of hours he works 43 in a week.
Simplify the radical by breaking the radicand up into a product of known factors
Exact Form:
2√10 + 5
Decimal Form:
11.32455532 . . .
Answer: 2√10 + 5
Hope this helps! :)
