X2y4(x2 - 16) - 9y4(x4 - 16) how do i simply this?
e-lub [12.9K]

Answer:

The simplified expression is given as

8x^2y^4(17x^2-2)

Step-by-step explanation:

step one:

Given the expression

x^2y^4(x^2 - 16) - 9y^4(x^4 - 16)

step two:

First, let us open the bracket we have

x^2y^4(x^2 - 16) - 9y^4(x^4 - 16)\\\\x^4y^4-16x^2y^4-9x^4y^4+144x^4y^4\\\\

step three:

collect like terms we have

x^4y^4-16x^2y^4-9x^4y^4+144x^4y^4\\\\x^4y^4-9x^4y^4+144x^4y^4-16x^2y^4\\\\-8x^4y^4+144x^4y^4-16x^2y^4\\\\136x^4y^4-16x^2y^4\\\\\\

step four:

we can now factor out 8x^2y^4we have

8x^2y^4(17x^2-2)

A hospital employs a total of 77 nurses and doctors. The ration if nurses to doctors is 9:2. How many nurses are employed at the
exis [7]

Answer: 63 nurses and 14 doctors

so you know the ratio is 9:2. that means for every 9 nurses there are 2 doctors. i didn't make an equation but i counted it.

if theres 9 (9*1) nurses theres 2 (2*1) doctors

if theres 18 (9*2) nurses theres 4 (2*2) doctors

if theres 27 (9*3) nurses theres 6 (2*3) doctors

you get the point so i multiplied 7 to 9 and 7 to 2, which means:

if theres 63 (9*7) nurses theres 14 (2*7) doctors

i hope this helps :)

Which strategy would you use to find 28?explain how you decided
Gelneren [198K]
You can do all strategies. Multiplication, Division, Addition, and Subtraction are the strategies because you can multiply 7 by 4 to get 28, divide 56 by 2 to get 28, add 14 by 14 to get 28, or subtract 40 by 12 to get 28.

Determine coefficients a and b such that p(x)=x2 ax b satisfies p(1)=5 and p′(1)=11.
Murrr4er [49]
p(x)=x^2+ax+b
p'(x)=2x+a

Given that p'(1)=11, you have

p'(1)=2+a=11\implies a=9

and given that p(1)=5, you have

p(1)=1+9+b=5\implies b=-5

So you get

p(x)=x^2+9x-5
