KiRa [710]

 8,262ft^2  of a single roll . Mr. Hanky have 5 roll so Total Area = 8,262(5) = 41,310 . So , 41,310ft^2 paper does Mr. Hanky have

<u>Step-by-step explanation:</u>

Here we have , Mr. Hanky has 5 rolls of butcher paper. If you roll out a whole roll the paper would  measure 510 yards long. If the paper is 1.8 yard wide .We need to find that how many total square feet of  paper does Mr. Hanky have . Let's find out:

We know that when butcher paper will be unfolded it will be in form of a rectangle with dimensions as :

Length = 510yards\\Breadth =1.8 yards

So , Area of rectangle = Length(Breadth)

⇒ Length(Breadth)

⇒ 510(1.8)

⇒ 918yards^2

But , 1 yard = 3 feet

⇒ 918(3ft)^2

⇒ 8,262ft^2

Therefore ,  8,262ft^2  of a single roll . Mr. Hanky have 5 roll so Total Area = 8,262(5) = 41,310 . So , 41,310ft^2 paper does Mr. Hanky have .

Answer:

a.) dx3x² + 2

Use the properties of integrals

That's

integral 3x² + integral 2

= 3x^2+1/3 + 2x + c

= 3x³/3 + 2x + c

= x³ + 2x + C

where C is the constant of integration

b.) x³ + 2x

Use the properties of integrals

That's

integral x³ + integral 2x

= x^3+1/4 + 2x^1+1/2

= x⁴/4 + 2x²/2 + c

= x⁴/4 + x² + C

c.) dx6x 5 + 5

Use the properties of integrals

That's

integral 6x^5 + integral 5

= 6x^5+1/6 + 5x

= 6x^6/6 + 5x

= x^6 + 5x + C

d.) x^6 + 5x

integral x^6 + integral 5x

= x^6+1/7 + 5x^1+1/2

= x^7/7 + 5/2x² + C

Hope this helps

(1)/(4p)(x-h)^(2)+k=0
erik [133]
Assume that p\ \textgreater \ 0 and <span>multiply the equation \frac{1}{4p} (x-h)^2+k=0 by 4p. Then you obtain the equation (x-h)^2+4pk=0.
</span>
1) If k>0, then 4pk>0 and the equation doesn't have solutions, because <span>(x-h)^2=-4pk and this is unreal.
</span>
<span>2) If k=0, then 4pk=0 and (x-h)^2=0. There is one solution x=h.
</span>
2) If k<0, then 4pk<0 and the equation
<span>(x-h)^2=-4pk>0 has two different solutions x_1=h+ \sqrt{-4pk} and x_2=h- \sqrt{-4hk}.</span>

What's the answer to 3/2(16n+3)=24n
ryzh [129]
N is equal to negative 4

3 times 2 IS 6
Take 6 times 16n then take 6 times 3
Now you have 96n plus 18 equals 24n
Subtract 96n from both sides
18 equals negative 72n
Divide both sides by 18 you get 4 now u can't have a negative n so divide each by a negative so now u have n equals -4
