Rob and lila try to simplify 18 x 4² + (9 - 3)². rob simplifies the expression and gets 360. lila simplifies it and gets 324. which student is correct? what error did the other student make?

Lila is correct and Rob is incorrect because she apply wrong property.    

Step-by-step explanation:

Given : Rob and Lila try to simplify  

Rob simplifies the expression and gets 360. Lila simplifies it and gets 324.

To find : which student is correct and what error did the other student.

Solution: First we simplify the expression:

The solution of the expression is 324 which means Lila simplifies correct.

The mistake is found in Rob,

She simplify   like and she put this in equation

 which is totally in correct.

because she use wrong property.

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
