Write two equivalent expressions to represent the area of the rectangle below.

Goshia [24]

Answer:

$A=(n-3)2\ units^2$

$A=(2n-6)\ units^2$

Step-by-step explanation:

we know that

The area of rectangle is equal to

$A=LW$

where

L is the length of rectangle

W is the width of rectangle

In this problem we have

$L=(n-3)\ units\\W=2\ units$

substitute

$A=(n-3)2\ units^2$

Apply distributive property

$A=2(n)-2(3)$

$A=(2n-6)\ units^2$

Please answer correctly !!!!!!!! Will mark brainliest answer !!!!!!!!!!!!!

spin [16.1K]

Answer & Step-by-step explanation:

Since you looking for the width and you are given the length and the area, then you will divide the area by the length.

(10x² + 5x) ÷ 5x

You can also turn this into a fraction so you can know what you are dividing.

$\frac{10x^2+5x}{5x}$

So, your width is 2x + 1

If the original cost of a TV is 1250.00 but decreases by 4.5% each week, how many weeks before the TV will cost 800.00?

NeX [460]

This is exponential growth/decay type problem...

F=Ir^t, F=final value, I=initial value, r=rate, t=time, in this case I=1250 and r=(1-.045)=0.955 so

F=1250(.955)^t and we want to find t for when F=800

800=1250(.955)^t

.64=.955^t take the natural log of both sides...

ln.64=t ln.955

t=(ln.64)/ln.995

t≈9.69 weeks

t≈9.69 weeks (to nearest hundredth of a week)
