Jacki evaluated the expression below. 2 cubed (3 minus 1) + 4 (8 minus 12) = 2 cubed (2) + 4 (4) = 8 (2) + 16 = 16 + 16 = 32. What was Jacki's error?

His error lies in  the subtraction of 12 from 8 , he wrote 4 instead of -4 , as 8-12 gives -4 instead of 4.

Step-by-step explanation:

Step 1

Rewriting this to a mathematical expression 2 cubed (3 minus 1) + 4 (8 minus 12) and solving correctly gives

2³(3-1)+ 4(8-12)

=8(2) + 4(-4)

= 16 +(-16)

16-16=0

Step 2Jacki's evaluation

2³(3-1)+ 4(8-12)

 = 2³(2) +4(4)

= 8(2) +16= 16+ 16 =32

His error lies in  the subtraction of 12 from 8 , he wrote 4 instead of -4 , as 8-12 gives -4 instead of 4.

I took the test ;)

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .
