Answer:
Step-by-step explanation:
hello :
let: A = 3√16+√-9
16=4² and -9 = 9i² =(3i)² .... ( i² = -1)
√16 =√4² = 4 and √-9 = √9i²= √(3i)² ± 3i
A= 12 ± 3i

Answer:
(2x+3)(x−4)
Answer:
C- 27
Step-by-step explanation:
Y varies directly as X
Y=kx
K is a constant
12=k16
K=12/16=3/4
Y=3/4x
Y=3/4 (36)
Y=27
Due to the lack of information I assume these are fractions so for 5/35 we times it by 21 and 21 by 35 so they have the same denominator so now we got 105/735 and for 21 we get x/735 so now You put 105/735 and divide by 35 so we get back down to 21 for
3/21 for part 1
Now for part 2 again 15 times 20 and 20 times 15 to equal out the denominators so now we have 240/300 and x/300 so now plug 240 into x and divide down by 15 and now we get
16/20 for part 2
LMK if I am wrong I highly doubt it
