d. 45

Answer 1

36-12x^2-3? if that is set equal to zero.
0=36-12x^2-3
-33=-12x^2
-33/-12= x^2
\[\sqrt{-33/-12}\] = 1.685 = x

Answer 2

P is for parenthesis (always do what is inside first)
E is for exponents
MD is multiplication and Division do it left to right (whoever is first)

AS is addition and subtraction do it left to right (whoever is first)
example 1-3+3=-2+3=1

Answer 12

@partyrainbow276 -->

36 - (8+4) *2 - 3 =
Do the ( ) first.
36 - (12) * 2 - 3 =
Do the multiplication next --> (12) * 2
36 - 24 - 3 =
Do subtraction next
12 - 3 = 9

Answer 13

I did it but i got 5.

Answer 14

Can you show your procedure? Maybe we can spot the problem

Answer 15

She is explaining this wrong as pellet.

Answer 16

i did 8+4=12 then 12x2= 24 then 24-36= 8 then -3 and got 5

Answer 17

and now im doing it again by myself

Answer 18

Thats where you are getting it wrong

Answer 19

you see 36-24 = 12 not 8 then, you substract by 3

Answer 20

=9

Answer 21

@partyrainbow276

i did 8+4=12 OK

then 12x2= 24 OK

then 24-36= 8 NOT OK --> Look at the problem: It is 36 - 24 which is 12.

then 12 -3 and you will get 9

Answer 27

check this one -15 bangor -18 bichmark 9 los angeles 15 miami hawain 19
Is this in right order? of integers

Answer 28

-18 is smaller than -15. On a number line, the smaller number lives to the left of the larger. -18 is to the left of -15 so -18 is smaller.

18 bichmark- 15 bangor - 9 los angeles 15 miami hawain 19
is how it goes.
