The formula would be 60 = 16 + 11n

Subtract 16 from 60 like this and cross out the 16 from the equation
60 = 16 + 11n
-16 X
___
44 = 11n

You then divide the 44 by 11 and cross out the 11 from the equation
44/11 = n

4 = n

You then get your answer

I hope this helped :)

Determine whether the polynomial below can be factored into perfect squares. If so, factor the polynomial. Otherwise, select tha

kkurt [141]

Answer:

A. $=(9x-12)^2$

Step-by-step explanation:

We need to determine whether the polynomial $81x^2-216x+144$ can be factored into perfect squares. If so, factor the polynomial. Otherwise, select that it cannot be factored into a perfect square.

$81x^2-216x+144$

$=9(9x^2-24x+12)$

$=9(9x^2-12x-12x+12)$

$=9(3x(3x-4)-4(3x-4))$

$=9(3x-4)(3x-4)$

$=9(3x-4)^2$

$=3^2(3x-4)^2$

$=(3(3x-4))^2$

$=(9x-12)^2$

Hence choice A. $=(9x-12)^2$ is correct.

Suppose g (x) is increasing and concave up everywhere and g(A)=7, gprime(A)=13, h=.01

rewona [7]

First we need a point (x,y) : (A, 7)
Now slope (from f'(A)) = 15 
Next, the equation (using point slope formula) 

y - 7 = 15 (x -A) 
y = 15 (x - A) + 7 

Now in the x spot we put 'A-.01' 
y = 15 ( A - .01 - A) +7= 15(-.01) +7 = -.15+ 7 = 6.85
hope this helps

What's the answer to the equation of 4x^2+25 and show yor work please and thank you

padilas [110]

4x^2+25=4x^2=-25=x^2=-25/4 has no solution. because, negative number do not live under radical except complex number
