Answer:138
Step-by-step explanation:
First plug in the c and d values into the expression:
6(5)^2-5(4)+8
Remember PEMDAS, so you do 5^2 first getting you 25.
6(25)-5(4)+8
Continue with PEMDAS and multiply -5 and 4, and that gets you -20.
150-20+8
Now you simplify the expression to get: 138.
56.30
With a calculator, press second or shift and then tan to find the degrees.
