9+2 = 11 11 = 1

7. 9•[8-2-3-(9-8)] 9-8 = 1
8-2-3 = 3 • 9 = 27+1 = 28

8. [7•3-(6+9)]/2= 6+9= 15
7•3 = 21 /2 = 10.5

9. 2•10/5+(7+5)/2= 7+5=12
2•10 = 20/2 = 10+12 = 22

10. 2•6-9-[5-(9-7)] 9-7 = 2
5-2 = 3
2•6= 12-9+3 = 3+3=6

11. 10+10/5-8 = 10/5 = 2
10-8+2= 2+2=4

12. [2-(10-8)]•6+3•5 = 10-8=2
2-2= 0 • 6 = 0+3•5 =15

13. 8/2/(6-4) = 6-4 = 2
8/2/2 = 4/2=2

14. 6[5+(14-8)/3] = 14-8=6 = 5+6/3= 2+5= 7•6 = 42

make sure you always use PEMDAS! those brackets are important too. once you do the problem inside the parentheses you go straight to the problem inside the bracket then move further on. please make brainliest :)!!

Find the area of the figure to the nearest hundredth.
Alecsey [184]

Answer:

=31.64ft^2

Step-by-step explanation:

Triangle

A=\frac{h_{b}b }{2} \\=\frac{4*6}{2}\\=12ft^2

Semicircle

A=\frac{\pi r^2}{2}\\=\frac{\pi 2.5^2}{2} \\=9.82ft^2\\

because both semicircle are the same just multiply by 2

9.82*2\\=19.64ft^2

Now add all together

12+19.64\\=31.64ft^2
