If c=5 and d=4
what is 6c squared minus 5d plus 8?

8.5

Step-by-step explanation:

The absolute value of anything is just it's positive number (the two little lines around d would be the symbol for absolute value). So, for example, the absolute value of -x would be x, and the absolute value for x would also be x. The definition of absolute value is the number away from zero that your value is.

(4r + 6.5) - | d |

(4(2) + 6.5) - | -6 |

(8 + 6.5) - 6

14.5 - 6

= 8.5
