Length of a rectangle is 5 cm longer than the width. Four squares are constructed outside the rectangle such that each of the sq

Arte-miy333 [17]

Answer:

The perimeter of rectangle is $18\ cm$

Step-by-step explanation:

Let

x------> the length of rectangle

y----> the width of rectangle

we know that

The area of the constructed figure is equal to

$A=xy+2x^{2} +2y^{2}\\A=120\ cm^{2}$

$120=xy+2x^{2} +2y^{2}$ -----> equation A

$x=y+5$ -----> equation B

substitute equation B in equation A

$120=y(y+5)+2(y+5)^{2} +2y^{2}\\120=y^{2}+5y+2(y^{2}+10y+25)+2y^{2}\\120=y^{2}+5y+2y^{2}+20y+50+2y^{2}\\5y^{2}+25y+50-120=0\\5y^{2}+25y-70=0$

using a graphing calculator to resolve the quadratic equation

the solution is

$y=2\ cm$

Find the value of x

$x=2+5=7\ cm$

Find the perimeter of rectangle

The perimeter of rectangle is equal to

$P=2(x+y)\\P=2(7+2)=18\ cm$

Okay, so you have the last option (g(x)=3^x+2-7) as your first line at that is aligned with the x-axis then movies up slightly into Quad. one. Your answer for this is going to be... C. g(x)=3^x-2-7.

You are going to graph these by using only a few selected points, then finding your answer.

Your horizontal Asymptote is y=-7.

x--------------y

-2 -6.988

-1 -6.963

0 -6.889
