Answer:
(5 - 7i)(8 + i)
F) 40 - 561
H) 37 - 371
K) -16 - 2i
G) -33 - 61i
J) 47 - 51i
- 9 below
Step-by-step explanation:
So we have lengths a and b and are given:
2a+2b = 66 => a+b = 33 => a= 33-b
a*b = 272
plug in one into the other:
(33-b)b = 272 => -b^2 +33b - 272 = 0
Can be factored as (b-16)(b-17) = 0, if you don't "see" this immediately, use the well known abc formula to find b.
So a=16 and b=17 or vice versa.
1/3,600 [explanation: (24 hours(60 mins))60 seconds)= 86,400 seconds -> 24/86,400 -> (24/86,400)/24 -> 1/3,600{
Y=12.5x
because 12.5 is the constant and this is a directly proportional equation
Answer:
60
Step-by-step explanation:
Is because when you have two negative -- signs it became positive
19 + 41 = 60
