That would be + 36

because

x^2 - 12x + 36 = (x - 6)^2

( you divide the -12 by then square the answer: -6^2 = 36 )

If x+1/x=7,find x^2+1/x^2

trapecia [35]

Answer:

x²+1/x² = 51

Explanation:

Given x - 1/x = 7 ---(1)

We know the algebraic identity:

a²+b²-2ab = (a-b)²

a²+b² = (a-b)²+2ab

Now,

x²+1/x²

= (x-1/x)²+2*x*(1/x)

= (x-1/x)²+2

:7²+2 [ from (1)] =

= 49+2

= 51

Therefore,

x²+1/x² = 51

ASHA 777 [7]

Answer:

$n=\frac{8}{3}$ or $n = 2\frac{2}{3}$

Step-by-step explanation:

Multiply both sides of the equation by $\frac{10}{3}$

$(\frac{10}{3}) (\frac{3}{10})*n= (\frac{10}{3})(\frac{4}{5})$

Simplify both sides of the equation.

$n=\frac{8}{3}$ or $n = 2\frac{2}{3}$

How do you explain how to get h(t)=7(t-25)

Nutka1998 [239]

Hey There! :)

To Solve for t.
$h(t)=7(t-25)$
Distribute the brackets.
$h(t)=7*t-7*25$
$h(t)=7t-175$
Subtract 7t from both sides.
$(h(t))-7t=(7t-175)-7t$
$(h(t)-7t=-175$
$h*t-7t=-175$
Factor out variable, t.
$t(h-7)=-175$
Divide both sides by h-7.
$(t(h-7))/h-7=(-175)/h-7$
$t=-175/h-7$

Hope this helps!

Solve 6x + 3) = 21.

LiRa [457]

Answer:

18x^2 - 9

Step-by-step explanation:

y = f(x)= 6x^3 - 9x + 4

dy/dx = d/dx(6x^3) - d/dx(9x) + d/dx (4)

=6.d/dx(x^3) - 9.d/dx (x) + d/dx. (4)

=6.3x^2 - 9.1 + 0 =18x^2 - 9
