Question

Simplify the expression: show all ur steps/ wrk PLEASE,1+2x3-18/3+(5(2+2)]

Answer 1

ok let's do this*pops knuckles*



let's add the first side


`1 + 2 * 3 - 18`
order of operations demands that we do multiplication first(P.E.M.D.A.S)

so

`2 * 3 = 6`
now we can add the 1 from

`1 + (6) - 18`
into our six



`6 + 1 = 7`
now we substract


`(7) - 18 = - 11`
now we have

`- 11 / 3 + (5(2 + 2))`
now we focus on the
other side

`3 + (5(2 + 2))`
since 5 is in paranthesis we use something called the distributive property. it mean we will multiply the 5 by both of the 2.

`(5(2 + 2)) = (((5 * 2) + (5 * 2) = 20`
now we have

`3 + 20 = 23`

(the three is from the original equation)

now we plug in our final numbers


`- 11 / 23`
or

`( - 11)/(23)`
I hope this helps

Answer 2

1+2x3-18/3+[5(2+2)]
1+2*3-18/3+[5(4)]
1+2*3-18/3+[5*4]
1+2*3-18/3+[20]
1+6-18/3+20
1+6-6+20
7-6+20
1+20
