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?

What is the value of 1/3x + 7x when x = 5

When using the linear combination metho e linear combination method to solve a system of linear equations, the four options are:

The customer price index(cpi), which measures the cost of a typical package of customer goods,was 208.8 in 2011 and 244.1 in 2016.let x=11 corresponding to the year 2011 an estimate to cpi into 2013 and 2014. assume that the data can be modeled by a straight line and the trend to continue idenfinitely.use data points to find such a line and then estimate the requested quantities
