Factor the expression. 16j2 + 24j + 9

rjkz [21]

Option C: $(4 j+3)^{2}$ is the correct answer.

Explanation:

The given expression is $16 j^{2}+24 j+9$

We need to factor the expression.

Let us rewrite the expression as

$(4j)^{2}+24 j+(3)^2$

Also, we can rewrite the term $24j$ as $2(4)(3)j$

Thus, we have,

$(4j)^{2}+2(4j)(3)+(3)^2$

Hence, the equation is of the form,

$(a+b)^{2}=a^{2}+2 a b+b^{2}$

where $a=4 j$ and $b=3$

Hence, the factor of the expression can be written as $(4 j+3)^{2}$

Thus, the factored expression is $(4 j+3)^{2}$

Therefore, Option C is the correct answer.

How do you find the derivative of y=ln(cos(x))y=ln(cos(x)) ?

makkiz [27]

$y=ln(cosx)\\\\We\ know:\\(lnx)'=\frac{1}{x}\ and\ (cosx)'=-sinx\ and\ \{f[g(x)]\}'=f'[g(x)]\cdot g'(x)\\\\therefore:\\\\y'=\frac{1}{cosx}\cdot(-sinx)=-\frac{sinx}{cosx}=-tanx$

All tangents to the circle are congruent and form a square. The perimeter of square ACEG is 24 cm. What is the length of line se

IrinaVladis [17]

Answer:

3 cm

Step-by-step explanation:

The perimeter of the square is 24 cm, so the side length is 6 cm.

I assume B is the point between A and C where the tangent line intersects the circle. If so, B is the midpoint of AC, so it is half the length. Therefore, BC = 3 cm.
