Trapezium area = (1/2(a+ b))xh where a and b are the two parallel lengths and h is the height.
semi cirlce area= (pi x r'2)/ 2
Answer:
numbers smaller than 3
Step-by-step explanation:
first expand the brackets so it will be :
24 -12x<6x - 30
then change < to =
24 -12x=6x - 30
24-18x= -30
-18x = -54
-x = -3
x = 3
then change symbols back so:
x < 3
Multiply by -4 on both sides.
this makes z<-8
So let x be the cost for board
12,584 = 1704+x+x
12,584 = 1704+2x
12,584 - 1704 = 2x
10,880 = 2x
10,880/2 = x
5,440 = x
So the turion cost is 1704 + x
Which is 1,704+5,440 = 7144
