Answer:

D 13

Step-by-step explanation: L+L+W+W=Perimeter

2(1/4x)+2(2x+1)=4.5x+2

4.5x+2=29 Subtract 2

4.5x=27 Divide by 4.5

x=6 1/4(6)= 1.5 W=1.5 1.5(2)=3

2(6)+1=13 13(2)=26

26+3=29inches perimeter

Answer:

A: 12 4/9

Step-by-step explanation:

1/4x (2x + 1) = 29 (Combine like terms, NOT distributive property!!!)

2 1/4x + 1 = 29

- 1 - 1

2 1/4 / 2 1/4x = 28 / 2 1/4

x = 12 4/9

Lim x--> 0 (e^x(sinx)(tax))/x^2

Tom [10]

Make use of the known limit,

$\displaystyle\lim_{x\to0}\frac{\sin x}x=1$

We have

$\displaystyle\lim_{x\to0}\frac{e^x\sin x\tan x}{x^2}=\left(\lim_{x\to0}\frac{e^x}{\cos x}\right)\left(\lim_{x\to0}\frac{\sin^2x}{x^2}\right)$

since $\tan x=\dfrac{\sin x}{\cos x}$ , and the limit of a product is the same as the product of limits.

$\dfrac{e^x}{\cos x}$ is continuous at $x=0$ , and $\dfrac{e^0}{\cos 0}=1$ . The remaining limit is also 1, since

$\displaystyle\lim_{x\to0}\frac{\sin^2x}{x^2}=\left(\lim_{x\to0}\frac{\sin x}x\right)^2=1^2=1$

so the overall limit is 1.
