Answer:

P=8x²+12y

Step-by-step explanation:

P=2L+2W; L=4x²-x+2y; W=x+4y; P=2(4x²-x+2y)+2(x+4y);

P=8x²-2x+2x+4y+8y; P=8x²+12y

Answer:

  • P = 8x² + 12y units

Step-by-step explanation:

<u>Given sides of rectangle:</u>

  • x + 4y
  • 4x² - x + 2y

<u>Its perimeter is:</u>

  • P = 2(l + w)
  • P = 2(x + 4y + 4x² - x + 2y)
  • P = 2(4x² + 6y)
  • P = 8x² + 12y

Multiply and simplify. 2x4yx⋅6xy2z3
OLEGan [10]

Answer:

The given expression 2x^4yx \times 6xy^2z^3   on multiplying  is 12x^6y^3z^3

Step-by-step explanation:

Consider the given two expressions 2x^4yx and 6xy^2z^3

We have multiply both expressions,

2x^4yx \times 6xy^2z^3

To multiply two terms first multiply constant numbers that is 6 × 2 = 12

For x , y and z apply property of exponent,

x^a\cdot x^b=x^{a+b}

Then power of x together will be,

x^4\cdot x\cdot x=x^{4+1+1}=x^6

Similarly for y powers,

y \cdot y^2=y^{1+2}=y^3

Since first term do not have any expression for z so it will remain same.

Thus, the given expression  on multiplying become,

2x^4yx \times 6xy^2z^3 is 12x^6y^3z^3

Hiram raises earthworms. In a square of compost 4 ft by 4 ft, he can have 1000 earthworms. How many earthworms can he have if hi
charle [14.2K]
64,000 I believe. What I did was find the area so 4*4 =16. 1000/16 = 62.5 earthworms per square foot. So if the side is 8 times longer then 8*4= 32 feet per side and to find the area of that it's 32*32 = 1024 feet squared. So 62.5 * 1024 =64,000

0.05% of 40 help please
ohaa [14]
0.05% of 40 is 0.02 

Divide your decimal by 100:
0.05 \div 100 = 0.0005

Multiply your decimal with 40:
0.0005 \times 40 = 0.02

Why does the graph of a function shift left when K is positive and to the right when K is negative?
Sedaia [141]

Answer:

You can visualize this easily.

y=f(x+h)

Now if the argument of the function is taken as (x−h) the value of y will be f((x−h)+h)=f(x)  

The function y acquires the value of f(x) at (x−h) amounting to a left shift.

Hope this makes things clear.
