There is no question in this.
First you can solve the triangle. complete the triangle my making the final side which would equal 12 because the top and bottom are bith 6. and the bottom is 12 then you do 1/2(12)(12) to find the area which would be 72. the area of the rectangle would be 18 so the total would be 90ft^2 when you add them together
One dice has 6 sides and two dice will give us 12 sides with 36 possibilities
it will be 9/36=.25
so it will have 25% chance of the two dice to have a sum of 9
Answer:
1. 3600 x 25 ÷100 =900
there fore the discount price is p900
3. it means if you add to integers you get 143
so x +x+1=143
2x +1=143
2x+1-1=143_1
2x=142
2x/2 =142/2
x=71
x+1=71+1=72
