(2x+4)^2 - (x-5)^2 = 26x<br> Please solve (explained)

Zina [86]

Expand the squared binomials:

$(2x+4)^2=4x^2+16x+16$

$(x-5)^2=x^2-10x+25$

Then

$(4x^2+16x+16)-(x^2-10x+25)=3x^2+26x-9=26x$

$\implies3x^2-9=0$

$\implies3x^2=9$

$\implies x^2=3$

$\implies x=\pm\sqrt3$

The equation P= 21 + 2w models the perimeter, P, of a rectangle with a length of / units and a width of w units.

natima [27]

Answer:

width = 10 units and length = 20 units

Step-by-step explanation:

Let the width be w

so Length will be 2w

using the rectangle formula:

$\sf Perimeter \ of \ rectangle= 2L + 2W$

$\sf 60= 2(2w) + 2w$

$\sf 60= 4w + 2w$

$\sf 60= 6w$

$\sf w = 10 \ units$

Find length:

$\sf length = 2w$

$\sf length = 2(10)$

$\sf length = 20 \ units$
