1. simplify 9(30 - 2). 2. find the value of -8 + 9 · 2 ÷ -3. (-2/3) (-2) (-11 1/3) (-14)

1. Remember to follow PEMDAS. First, solve the parenthesis, then multiply by 9

30 - 2 = 28

28 x 9 = 252

252 is your answer for your first question

2. Again, follow PEMDAS & left -> right rule. First, solve for multiplication, then division, and finally addition.

First, multiply: 9 x 2 = 18

Next, divide: 18/-3 = -6

Finally, add: -8 + -6 = -8 - 6 = -14

-14 is your answer

~

#1. =252.  #2. -14. On #1. *The answer should be positive sign.* On #2. *The answer should be have negative sign.*

Step-by-step explanation:

1.

#1 and #2. This question it's about PEMDAS. This lesson it's about order of operations. p-parenthesis, e-exponents, m-multiply, d-divide, a-add, and s-subtract. It can also go left to right.

calculate parenthesis first.

9(30-2)

multiply left to right.

9*28

=252

252

2. -8+9*2/-3

9*2/-3=-6

-8-6

subtract by the numbers.

8+6=14

=-14

=-14

Hope this helps!

Thanks!

Have a great day!

60 square cm.

Step-by-step explanation:

The total is 132 cm.

To find the awnser to the are of the shaded part you just do 10 times 6 which equals 60.
