The function W (x)=0.5x^2 gives the number of servings of a wedding cake that can be obtained from a two layer X inch square wedding cake tier what size square wedding cake tier is needed to serve eight people

4in² cake

Step-by-step explanation:

Given the function W (x)=0.5x^2 gives the number of servings of a wedding cake that can be obtained from a two layer X inch square wedding cake tier, to get the size needed to serve 8 people, we will substitute W(x) = 8 into the expression and find x as shown;

W(x)=0.5x^2

8 = 0.5x^2

8/0.5 = x^2

8*2 = x^2

16 = x^2

Rearrange

x^2 = 16

x = √16

x = 4 in²

Hence the size of the wedding cake needed to serve 8 people is 4in² cake
