(x-4)•2 < 9
the difference between x and 4 means to subtract
and twice that means to double or times by 2
and all that’s LESS than 9
so the sign opens up towards the 9
Step-by-step explanation:
Kayden:Kayah:Kayla:Michelle
2:3:4:3
2k+3k+4k+3k=36
12k=36
k=36:12
k= 3
Kayden- 2•3=6
Kayah- 3•3=9
Kayla= 4•3=12
Michelle= 3•3=9
A because it’s the right answer
Answer:
335.115
Step-by-step explanation:
First you find the area of the circles to do that you do pi times radius squared
For the top square do 3.14(pi)time 3²=28.26
For the middle square do 3.14 times 4.5²=63.585
For the bottom square do 3.14 times 6²=113.04
Now find the area of the entire thing do 18×12+9+6+3=18×30=540
Finally do 540-the area of the squares 28.26-63.585-113.04= 335.115
So the shaded region is 335.115
Hope this helps and have a great day!
