2d^3+3c^2+5 d equals 4 and c equals 3

Lets get started :)

2d³ + 3c² + 5

The given:
d = 4
c = 3

We substitute the given into the original!
   2(4)³ + 3(3)² + 5
= 2(64) + 3(9) + 5
= 128 + 27 + 5
= 160

Let's do this.

First you have to analyse the informations given.

It says : c = 3 and d = 4.

Now you merely have to substitute these two numbers in the expression given.

It gives :

2d³ + 3c² + 5
= 2(4)³ + 3(3)² + 5
= 2*64 + 3*9 + 5
= 128 + 27 + 5
= 160.

In short, the answer is 160.

Hope this helps !
