In expansion of (2x+1)(x^2+px+4), the coefficient of x is twice the coefficient of x^2.

Brilliant_brown [7]

You're probably supposed to find the value of p and not x, which is impossible to do.

Expanding gives

$(2x+1)(x^2+px+4)=2x^3+(1+2p)x^2+(8+p)x+4$

We're told that

$8+p=2(1+2p)$

which we can use to solve for p:

$8+p=2+4p$

$6=3p$

$\boxed{p=2}$

Solve for x. The polygons in each pair are similar.

VMariaS [17]

Answer:

x = 9

Step-by-step explanation:

We need to find the value of x if the polygons in each pair are similar.

As they are similar, the ratio of their sides are equal.

The sides of first polygon are 6,12 and 4.8. On the other hand, the sides of second polygon are (2x-9) and 18.

So,

$\dfrac{6}{2x-9}=\dfrac{12}{18}\\\\\dfrac{6}{2x-9}=\dfrac{2}{3}\\\\\dfrac{3}{2x-9}=\dfrac{1}{3}\\\\x=9$

So, the value of x is equal to 9.
