Mr. Chen writes the expression 4 x (7 - 2)*2 divided by 10 on the board. Keisha said the first step is to evaluate the exponent. Explain keisha’s mistake, and then evaluate the expression. PLEASE HELP!!!

Show algebraically that f and g are inverse functions f(x)=x^2/-6; g(x)=square root of 2x+12

What is the simplified expression for 6(2(y+x))

1c) the number 131 is a term in the sequence defined by the explicit rule f(n)=5n-4. which term in the sequence is 131? 2a) write the first four terms of the function f(n)=n^2-1 2b) what is the 10th term of the sequence defined by the explicit rule f(n)=n^2-1 2c) the number 224 is a term in the sequence defined by the explicit rule f(n)=n^2-1. which term in the sequence is 224?
