Answer:

x² + x = 42

Step-by-step explanation:

Let the number be x then the square of this number is x²

Sum and equate to 42, that is

x² + x = 42

The cost of ordering multiple items is sometimes, always or never proportional
AlladinOne [14]
Unless there is no promotion like "buy 2 get 1 free" or "buy 2 get 1 for 50%" etc. then the cost of ordering multiple items is always proportional. Let's say something costs $5. Two items will cost $10, three $15, four $20 etc. These numbers are all proportional. Hopefully that's what you meant :)

GEOMETRY PLEASE HELP ME URGENT
Basile [38]
Converse (switch p and q)
If an angle is obtuse, then it measures 128°

This is false (a 127° angle is obtuse, but it does not measure 128°)

_____________________________________________________________

Inverse
(negations of p and q)
If an angle does not measure 128°, then it is not obtuse

This is false (a 127° angle does not measure 128°, but it is obtuse)

_____________________________________________________________

Contrapositive (negations of p and q, then switch their places)

If an angle is not obtuse, it does not measure 128°

This is true (any 128° is obtuse; no exceptions)

Please answer this correctly

Answer: 2/3

Step-by-step explanation:

There are three sectors of equal area. 2 is one of the sectors. You can get 3 and 4. There are two total cases out of 3, so it's 2/3

Hope that helped,

How to solve<br> -22-x=5+6x+9
nadya68 [22]
  -22 - x = 5 + 6x + 9   Combine like terms (5 and 9)
  -22 - x = 14 + 6x        Subtract 6x from both sides
-22 - 7x = 14                Add 22 to both sides
        -7x = 36               Divide both sides by -7
           x = 5\frac{1}{7}

The function of the length z in meters of the side parallel to the wall is A(z) = z/2(210 - z)

<h3>How to write a function of the length z in meters of the side parallel to the wall?</h3>

The given parameters are:

Perimeter = 210 meters

Let the length parallel to the wall be represented as z and the width be x

So, the perimeter of the fence is

P = 2x + z

This gives

210 = 2x + z

Make x the subject

x = 1/2(210 - z)

The area of the wall is calculated as

A = xz

So, we have

A = 1/2(210 - z) * z

This gives

A = z/2(210 - z)

Rewrite as

A(z) = z/2(210 - z)

Hence, the function of the length z in meters of the side parallel to the wall is A(z) = z/2(210 - z)
