Roger's evaluation of an expression is shown.

2(1+3)^3-5^2=

step 1: 2(4)^3-5^2=

step 2: (8^3)-5^2=

step 3: 24-10=

step 4: 14

describe all of the errors roger made with his work, then correctly evaluate the expression.

my 2(1+3)^3-5^2=
4
2*4^3-5^2=
2*64-25=
128-25=103

how do i describe what he did wrong?

make sure you have version 2.50

try looking in the very back of the book : )

step-by-step explanation:

you can download it here

113.42

i hope that is right.

step-by-step explanation:

glad to

it is g.

step-by-step explanation:

ad does increase as the sales increases so g. is right.

j. it really kick itself off because it says " always " .

h. nothing remains that same, everything changed through out the graph!
