What is the solution to the equation below. square root x - 6 = x - 12

lyudmila [28]

$\\ \rm\hookrightarrow \sqrt{x-6}=x-12$

$\\ \rm\hookrightarrow x-6=(x-12)^2$

$\\ \rm\hookrightarrow x-6=x^2-24x+144$

$\\ \rm\hookrightarrow x^2-25x+150=0$

$\\ \rm\hookrightarrow x^2-10x-15x+150=0$

$\\ \rm\hookrightarrow (x-10)(x-15)=0$

$\\ \rm\hookrightarrow x=15\:or \:10$

What is the surface area of the square pyramid below?

Reika [66]

The surface area of square pyramid is the sum of the area of all its sides.

If l is the slant height and base is s each then surface area of pyramid is given by:

Surface area = s2+2xsx l

From the given figure in the question:

S=6 cm ,l= 8cm.

Substituting these values in surface area formula we have:

Surface area = 62+2x6x8

Surface area = 36+96

Surface area =132cm2
