Answer:
Two ways you can group them is:
(4+7)+2
4+(7+2)
They will both give you the same answer of 13.
(4+7)+2 4+(7+2)
11+2= 13 4+9= 13
50. since n_1/4<1 the equation is not true. it has no solution.
48. same thing since 45 <= z the equation is not true.
The answer is B.
For an expression to be a polynomial term, any variables in the expression must have whole number powers.
-3/x isn’t a polynomial term because the variable is in the denominator.
Answer:
Evaluating Exponents. An exponent is a number that tells how many times the base number is used as a factor. For example, 34 indicates that the base number 3 is used as a factor 4 times. To determine the value of 34, multiply 3*3*3*3 which would give the result 81
