Question

I need help!

I'm not really look for the answers, just need help doing step by step. Here's the problems:

1.) 28/[3-(1/2)*-8]+1

2.) 2(3x-y)+3(y-z)

3.)8x-2(4y+1)-(3y)/3

4.) If the length of the rectangle is (3x-2)units and the width is 3 units, Find the perimeter of the rectangle,

Answer 1

Look at order of operations

starting inside paentheses the power function is first

so looking at denominator

[3-256]+1= -252

so 28/252 = 1/9
