Answer:

Step-by-step explanation:

Width = w units

Length = ( w + 13 ) units

Perimeter of rectangle = 38 units

2* (length + width) = 38

2*(w +13 + w )= 38 {Use distributive property: a*(b+c)=(a*b) +(a*c)

2* ( 2w + 13) = 38

2*2w + 2*13 = 38

4w + 26 = 38 {Subtract 26 from both sides}

4w = 38 - 26

4w = 12 {Divide both sides by 4}

w = 12/4

w = 3 units

Length = 3 + 13 = 16 units

Select the basic integration formula you can use to find the indefinite integral.

kondaur [170]

Answer:

$\int \dfrac{du}{u}=\log|u|+C$

$\int u^n du=\dfrac{u^{n+1}}{n+1}+C$

$\int \dfrac{du}{u\sqrt{u^2-a^2}}=\dfrac{1}{a}\csc^{-1}(\dfrac{x}{a})+C$

Step-by-step explanation:

$\int \dfrac{du}{u}=\log|u|+C$ $[\because \int \dfrac{dx}{x}=\log |x|+C]$

$\int u^n du=\dfrac{u^{n+1}}{n+1}+C$ $[\because \int x^n dx=\dfrac{x^{n+1}}{n+1}+C]$

$\int \dfrac{du}{u\sqrt{u^2-a^2}}=\dfrac{1}{a}\csc^{-1}(\dfrac{x}{a})+C$ $[\because \dfrac{adx}{x\sqrt{x^2-a^2}}=\csc^{-1}(\dfrac{x}{a})+C]$

Question 7 i mark as brainliest

gogolik [260]

2 1/2 should be the answer. Adding all of the x’s up you’ll get 16.5. Since you need 19 oz take 19 and subtract 16.5 to get 2.5. Convert 2.5 into a mixed fraction and get 2 1/2
