Answer 1

(x-1) (6x^2 -1)

Answer 2

if u like the answer ...pls fan me ..thanx

Answer 3

then I have another one to see if it is correct I have 6^6-64

Answer 4

my answer (b+2)(b^2-2b+4)(b-2)(b^2-2b+4)

Answer 5

r u typing?

Answer 6

hello, r u there?

Answer 7

yes I am here

Answer 8

Small ever in that factorisation: one of the (-2b) should be +2b

Answer 9

i m waiting for the question

Answer 10

error* eugh

Answer 11

b^6-64

Answer 12

oh ok

Answer 13

OK, Ignore me then... ¬_¬

Answer 14

its (b-8)(b+8)

Answer 15

because of (a^2 - b^2) =( a-b) (a+b)

Answer 16

it should (b+2)(b^2-2b+4)(b-2)(b^2+2b+4)

Answer 17

Answer 46

u there?

Answer 47

I have a question polynomial 0.041h-0.018a-2.69 can be used to estimate the lung capacity, in liters of a female with height h, in centimeters, and age a, in years. Find the lung capacity of a 30 year old woman who is 170 centimeters tall. Her lung capacity is approximately_____ liters?

Answer 48

I am confused on how you go about figuring out this problem

Answer 49

Lung Capacity (h, a) = 0.041h-0.018a-2.69

Let h = 170 , a = 30

=> Lung Capacity (170, 30) = 0.041 x 170 - 0.018 x 30 - 2.69

Answer 50

the answer would be 206 liters

Answer 51

0.041 x 170 - 0.018 x 30 - 2.69 = 3.74...

Answer 52

ok i see what i did wrong

Answer 53

Was your mistake considering the possibility that my advice was incorrect?

Answer 54

what i did was took 0.041* 170=6.97-.018=6.952*30=208.56-2.69=205.87

Answer 55

Ah, I see; glad you sorted it.

Answer 56

but if you do the mutliplication first 0.041*170=6.97 & .018*30=.54 then you subtract 6.97-.54-2.69=3.74
