Answer:
9-25i is equivalent to (−3+5i)(−3−5i)
Answer:
19. A
20. A
Step-by-step explanation:
19. tan(53)=15/x
x(tan(53))=15
x=15/(tan53))
x=11.3 feet
20. tan(60)=12/x
x(tan(60))=12
x=12/(tan(60))
x=6.93, or 4sqrt3
Hmm it would be k(x)=2(5x) or it could be k(x)=10x
Hope this helps!
The answer is: 70 .

Explanation:
_________________________________
(20/100) x = 14; solve for "x".
(20/100) = 2/10 = 1/5 ;
(1/5) x = 14
x/5 = 14 ;
x = 14 * 5 ;
x = 70 . The answer is: 70 .

Answer:
The answer would be 2.7. Am not very sure though
Step-by-step explanation:
So what you do is
for example the unkown number is x and the answer you get is y
12-x=y * -15=-140
-140/-15=9.33 (this is y the answer)
12-x=9.3
12-9.3=2.7
To check your answer
12-2.7=9.3
9.3 * -15=-139.5 if you round it then it would be -140
