Using the midline property;





(10x+5)4 = 30x + 3x + 6x +30
40x + 20 = 39x + 30
X = 10
perimeter of the square= 420
perimeter of the triangle= 420
Answer:
If this is FLVS every lesson has I think its called "Function question" underneath is a question. Thoes questions are for the dba. There are questions at the top of every page of every lesson. Look uo the answers for them! or use the notes most of the time they give you answer to them already. I hope that helps of you have any other questions feel free to ask <3
First convert all the units into millimetres.
1 metre = 1000 millimetres
10 metres = 10000 millimetres
2 : 1000 :: x : 10000
Remember this: <u><em>Product of means is equal to the product of extremes.</em></u>
<u><em></em></u>
2 × 10000 = 1000x
20000 = 1000x
∴ x = 20000 ÷ 1000
x = 20 millimetres
