Well okay first you want to write the expression.
6c²-5d+8 (next you replace the c with 5 and d with 4)
6(5)²-5(4)+8 (now you want to go left to right, first you want to do 5²) 6(25)-5(4)+8 (like always left to right :D ** 6 × 25**) 150-5(4)+8 (5 × 4, then 150· 5×4 ) 150-20+8 130+8 (Now you add :D ) 138
Final answer is 138
I hope I helped you out! :D

If u substitute in the values, c=5 and d=4 into the expression, u get 6(5)^2-5(4)+8 =6(25)-20+8 =150-20+8 =130+8 =138

After substituting c = 5 and d = 4 into the expression 6 c 2 − 5 d + 8 , we calculated the value step-by-step. The computations lead us to the final value of the expression, which is 138. Thus, the answer is 138.
