Question

Evaluate: 6x2 + (9y-2)+y when x= 3 and y=8.

Answer 1

Answer:

98

Step-by-step explanation: All you have to do is multiply 6 by 3 and then multiply that answer by 2. Then you multiply 9 by 8 and subtract 2, then you add all that together and finally, subtract it by 8

Answer 2

Answer:

The answer is 402.

Step-by-step explanation:

First thing to do is substitute the variables.

6(3)^2+(9(8)-2)+8

Now, multiply and subtract what is in the parenthesis.

6(3)^2+(72-2)+8

6(3)^2+70+8

Now, multiply once again.

18^2+70+8

Now, simplify the exponents.

324+70+8=402
