What is 9+9(2+4)÷3-2 equal
lesantik [10]
First, we must follow PEMDAS. (Parenthesis, exponents, division, multiplication, addition, and subtraction.).

We do what's in the parenthesis first.

9+9(2+4)÷3-2.

2+4=6.

Now our problem looks like this;

9+9(6)÷3-2 
OR
9+9×6÷3-2.

Anything in a parenthesis with no sign next to it, like this; 8(2), just means multiplication, so it would look like this: 8×2.

Next, we do all the multiplication in our problem.

9+9×6÷3-2.

9×6=54.

Now our problem looks like this;

9+54÷3-2.

Next, we do the division. 

9+54÷3-2

54÷3=18.

Now our problem looks like this;

9+18-2.

Next, we do the addition.

9+18-2

9+18=27

Now it looks like this;

27-2.

Finally, we subtract.

27-2=25.

Your final answer is 25!

Have a nice day! :)

Find the value of x for which ABCD must be a parallelogram.
Inessa [10]
Hey there!

You can tell that the two angles are congruent because of the arc. So make the two angles each other.
3x-17=25-3x. Add 3x to each side. You get 6x-17=25. Add 17 to each side to get 6x=42. Divide each side by 6. You get x=7. So the value of x would be 7.

I hope this helps!
