Answer:
Step-by-step explanation:
(-5x^2+12)/4. When x=-3
= {-5(-3)^2 +12}/4
= (-5(9) +12)/4
= (-45 +12)/4
= -33/4
= -8 1/4
Answer:
8.25
Step-by-step explanation:
exponents then multiply/divide then add/subtraction & of course if it is in *parentheses*, its first (and always go fro left to right)
(-5*(-3^2)+12)/4
exponents: -3^2=-3*-3=9
and then multiply -5*9=-45
then add -45+12=33
and then because of the parentheses, *now* divide 33/4=8.25
