welcome to the forum

Is this the Maths Papers you are talking about?

If you could post the questions I am sure someone will be able to help.

Q50 is
Ben and Emma each start to grow a plant on the same day.
After one week both plants are 5cm tall . During the next three weeks Bens plant grows f cm's per week and Emma's plant grows g cm's per week.
Emma's plant is taller.
When the plants are both 4 weeks old how much taller is Emma's plant than Ben's in cm's

and Q 48 is a drawing of a hexagon with the radius coming to the middle of one of the sides (unsuccessfully
tried to copy n paste) and the question is
What is the formula for the area of this shape?
answers range from
3(xy)
6x+6y
3xy/2
6x+6y/2
6(xy)

Thank you

Q48 is 3(xy)
If I've understood correctly, it's a regular hexagon. Therefore it comprised 6 regular triangles with x and y being the lengths of two of the sides.
The area of a triangle is 1/2 (base x height) or in this case 1/2 (xy)
Multiply by 6 as there are 6 triangles in the hexagon = 3(xy)

Brain shutting down and can't think straight, :roll: will try to look at first question tomorrow

Awe thank you that is great...
School is sending past test home for homework but
Forgetting to go over any they are stuck with. So you ask
Yourself where is the logic, your Childs life in their hands.
