3) 0.5(12m-22n)=0.5(12m)-0.5(22n)
=6m-11n
4) 2/3(18x+6z) =2/3(18x)-2/3(6z)
=12x-4z
5)2x+12=2(x+6)
6)12x+24=12(x+2)
It gets you closer to your answer.
Ex: 11×2-- Round 11 to 10 and then multiply and get 20. But if you get some answer like 50, you know it is wrong. But the answer is 23

Hi!
<h3>Put in the values. </h3>
[z+8(5-2)]^2/4
<h3>Now use PEMDAS to solve. </h3>
- Parentheses - Subtraction
[z+8*3]^2/4
- Parentheses - Multiplication
[z+24]^2/4
z+576/4
<u>z+144</u>
<h2>When you evaluate [a+8 (b-2)]^2÷4, you get z + 144</h2>
Hope this helps! :)
