Simplify the expression given below. x+2/4x^2+5x+1 * 4x+1/x^2-4

GenaCL600 [577]

Answer:

$\frac{1}{(x+1)(x-2)}$

Step-by-step explanation:

$\frac{x+2}{4x^2 + 5x + 1} \ \times \ \frac{4x+1}{x^2-4}\\\\=\frac{x+2}{4x^2 + 4x + x + 1} \ \times \ \frac{4x+1}{x^2-2^2}\\\\=\frac{x+2}{4x(x + 1) + 1( x + 1)} \ \times \ \frac{4x+1}{(x - 2)(x + 2)} \ \ \ \ \ \ \ \ [ \ (a^2 - b^2 = (a-b)(a+b) \ ]\\\\\\=\frac{x+2}{(4x + 1)(x+1)} \ \times \ \frac{4x+1}{(x-2)(x+2)}\\\\=\frac{1}{(x+1)} \ \times \ \frac{1}{(x-2)}\\\\= \frac{1}{(x+1)(x-2)}$

What is the length of CD? In this diagram, AABC ~ AEDC. 20-% c * 7 21

d1i1m1o1n [39]

Answer:

$\frac{BC}{DC}=\frac{AC}{EC}$

$\frac{20-x}{x} =\frac{21}{7}$

$\frac{20-x}{x} =3$

$20-x=3x$

$4x=20$

$x=5$

$So, CD=5$

Find the equation of the plane through the point p=(2,3,4)p=(2,3,4) and parallel to the plane 5y−5x−5z=4.

Lostsunrise [7]

Find plane Π parallel to 5y-5x-5z=4 containing point p=(2,3,4)

Any plane parallel to 5y-5x-5z=4 has the form 5y-5x-5z=k, or on simplification, y-x-z=k.

Since p lies in the plane, the coordinates of p must satisfy y-x-z=k, or
k=3-2-4=-3
=>
π : y-x-z=-3
equivalently,
π : 5y-5x-5z=-15
