Answer:
Step-by-step explanation: Two solutions were found :
a =(4-√-24)/-2=2+i√ 6 = -2.0000-2.4495i
a =(4+√-24)/-2=2-i√ 6 = -2.0000+2.4495i
Answer:
C
Step-by-step explanation:
Answer:452.16m^2
Step-by-step explanation:
C=2πr
75.36m=2×3.14×r
75.36m=6.28r
r=12m
Area=πr^2
A=3.14×12m×12m
A=452.16m^2
Answer:
Marc's age is 12
Step-by-step explanation:
Let
x ----> Marc's age
y ---> Tony's age
z ---> Ben's age
we know that
the sum of their ages is 40
so
-----> equation A
Marc is half as old as Tony
so
----> equation B
Marc is three times as old as Ben
so
----> equation C
substitute equation B and equation C in equation A
solve for x
therefore
Marc's age is 12
