The proof that the area of the trapezium is 2x² + x -351 = 0 can be seen in the image attached below.

<h3>What is a trapezium?</h3>

A trapezium is a quadrilateral that has a pair of opposite parallel sides.

From the given diagram:

The area of the trapezium can be computed as;

\mathbf{= \dfrac{1}{2} \times (sum  \ of \  the \  parallel \  sides) \times height }

\mathbf{351= \dfrac{1}{2} \times (x-4 + x +5) \times 2x  }

\mathbf{351= \dfrac{1}{2} \times (2x+1) \times 2x  }

\mathbf{351=  (2x+1) \times x  }

351 = 2x² + x

2x² +x - 351 = 0    : Proved

If 17 subs were shared by 22 children fairly, about how much of a sub would each child receive. Is tis amount 1/2, 3/4, or 2/3?
Ray Of Light [21]

<u>Answer</u>

3/4


<u>Explanation</u>

There are 17 subs that are to be shared between 22 children. To get that we divide 17 by 22.


∴ 17 ÷ 22 = 17/22


               = 0.77272727...

From the choices we can get the closest fraction by converting them to decimals.

1/2 = 0.5

The difference from the correct answer = 0.77 - 0.5 = 0.27

3/4 = 0.75

The difference from the correct answer  = 0.77 - 0.75 = 0.02

2/3 = 0.67

The difference from the correct answer is 0.77 - 0.67 = 0.1.

The closest amount is 3/4 since it has the least deviation of 0.02 from the correct amount.
