Answer:
70cm
Step-by-step explanation:
Area of triangle: (5.8x4)/2=11.6
Area of big rectangle: 8x5.8=46.4
Area of small rectangle: 2.4x5=12
12+46.4+11.6=70
To factor you have to do this:
s^2 + 9s = -20
+ 20 +20
s^2 + 9s + 20 = 0
now you need to numbers that multiplied give you 20
and then those same 2 numbers have to add to 9
5 x 4 = 20
5+ 4 = 9
(x + 4) (x+ 5)
that means that x= -4, and -5
Answer:
mean= 8.8
median= 9
mode= 9
range= 10
