Answer:

trapezoid.

Step-by-step explanation:

A trapezoid is a convex quadrilateral. A trapezoid has at least on pair of parallel sides. the parallel sides are called bases while the non parallel sides are called legs

Characteristics of a trapezoid

It has 4 vertices and edges

If both pairs of its opposite sides of a trapezoid are parallel, it becomes a parallelogram

Area of a trapezoid = \frac{1}{2} x (sum of the lengths of the parallel sides) x height

Perimeter =  sum of lengths of sides of a trapezoid

This system of equations has an infinite number of solutions. Define the solutions algebraically, and allow z to represent all r
Soloha48 [4]

Answer:

x = 12z + 1  and y = 10z - 1

Step-by-step explanation:

To solve the system of equations, we can use the substitution method

If we call

3x - 4y + 4z = 7 I

x - y - 2z = 2 II

2x - 3y + 6z = 5 III

Clearing II  x = 2 + y + 2z

Now, replacing II in III

2(2 + y + 2z) - 3y +6z = 5

4 + 2y + 4z - 3y + 6z = 5

10z - y = 1 from here y = 10z - 1

Finally, replacing y in I

3x - 4(10z - 1) + 4z = 7

3x -40z + 4 + 4z = 7

3x - 36z = 3

3x = 36z + 3

x = 12z + 1

Harlamova29_29 [7]

For this case, the first thing we should do is take into account the following conversion:

1L = 1000ml

Therefore, the 25 ml dose number is given by:

N = \frac {1000} {25}\\N = 40

Answer:

The number of doses that can be obtained from a bottle of 1 liter of vegetable food is:

N = 40
