Solve the equation, if possible. (If all real numbers are solutions, enter REALS. If there is no solution, enter NO SOLUTION.)

Masteriza [31]

Answer:

The equation $x\left(x\:+\:6\right)\:=\:\left(x\:+\:3\right)^2$ has NO SOLUTION, and is called contradiction.

Step-by-step explanation:

Given the equation

$x\left(x\:+\:6\right)\:=\:\left(x\:+\:3\right)^2$

$\mathrm{Expand\:}x\left(x+6\right):\quad x^2+6x$

$\mathrm{Expand\:}\left(x+3\right)^2:\quad x^2+6x+9$

$x^2+6x=x^2+6x+9$

$\mathrm{Subtract\:}x^2+6x\mathrm{\:from\:both\:sides}$

$x^2+6x-\left(x^2+6x\right)=x^2+6x+9-\left(x^2+6x\right)$

$\mathrm{Simplify}$

$0=9$

$\mathrm{The\:sides\:are\:not\:equal}$

Thus, there is NO SOLUTION.

We know that an equation that has no solution, such as $x = x + 2$ , is called a contradiction.

Therefore, the equation $x\left(x\:+\:6\right)\:=\:\left(x\:+\:3\right)^2$ has NO SOLUTION, and is called contradiction.

Find the curved surface area of a cylinder diameter 12cm and length 30cm (fast plz)

Effectus [21]

Answer:

solution:-

diameter of a cylinder (d) = 12 cm

length(h) = 30 cm

curved surface area of cylinder (csa) = ?

we know that ,

therefore , csa of cylinder = 2πrh

r = d/2

or, r = 12/2= 6 cm

Then, csa if cylinder = 2 ×22/7×30

= 2×22×30/7

= 1320/7

= 188.57 Square cm Ans,......
