Question

9 solve the following equation when d = 2 and c = 6. 8d² + 5c + 3 =

Explanation:

Step1: Substitute d = 2 into \(8d^2\)

First, calculate \(d^2\) when \(d = 2\), so \(d^2=2^2 = 4\). Then multiply by 8: \(8\times4=32\).

Step2: Substitute c = 6 into \(5c\)

Calculate \(5\times6 = 30\).

Step3: Add all terms together

Now add the results from Step1, Step2, and the constant 3: \(32+30 + 3=65\).

Answer:

65
