Order of operations could someone me with this question? because i don't know how to completely work it out
2^2-2(-2-2)-3^3

-15

Step-by-step explanation:

so to start you must distribute negative two times negative two equals positive four,

so now your equation looks like this,

2^2 +4+4-3^3

then you need to do the exponents,

2 x 2 = 4

3 x 3 x 3 =27

now it looks like this

4+4+4-27

12 - 27

-15

Hope that helps!

i can

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
