The area of a rectangle is given by:
Area = length x width
Length = 4/3 w
432 = 4/3 x w²
w = 18 inches

Area= Length x width
So....
Length= Area divided by width.
Plug in equation
20 divided by 5= L
L= 4
Answer is 4 cm

Answer:

3) x=4 4)x = 9 5) x=5

Step-by-step explanation:

3) first you have to find the inside of the angle. A straight line = 180*

180-(19x+3) = 177-19x

Than you add all the angles up to equal 180.

(177 - 19x) + (11x-2) + (9x+1) = 180

if you simplify this x = 4. You can check your answer by subbing in for x.

4)first you have to find the inside of the angle. A straight line = 180*

180- (17x-23) = 203-17x

Than add the sides up to equal 180. keep in mind there are 2 of the same angles.

(203-17x)+(7x+2)(2) = 180

Simplify

x=9

5) 180-151=29* this is the inner angle.

(11x-1)+(20x-3)+29=180

31x+25=180

x=5

[(1/(3+x))-(1/3)] / x<br> Limit 0

Effectus [21]

First find a common denominator and combine the fractions in the numerator:

$\displaystyle\lim_{x\to0}\frac{\dfrac1{3+x}-\dfrac13}x=\lim_{x\to0}\frac{\dfrac3{3(3+x)}-\dfrac{3+x}{3(3+x)}}x=\lim_{x\to0}\frac{3-(3+x)}{3x(3+x)}$

Now simplify and cancel out all the terms that you can:

$\displaystyle\lim_{x\to0}\frac{3-3-x}{3x(3+x)}=-\frac13\lim_{x\to0}\frac1{3+x}$

Since the remaining expression is continuous as a function of $x$ , you can directly substitute to end up with

$\displaystyle-\frac13\lim_{x\to0}\frac1{3+x}=-\frac13\times\frac1{3+0}=-\frac19$
