Answer:
How to Calculate a Rate. "Rate" simply means the number of things per some other number, usually 100 or 1,000 or some other multiple of 10. A percentage is a rate per 100. Infant mortality rates are calculated per 1,000.
Step-by-step explanation:
If you mean 2 and 3 it would be (x-2)(x-3)=0
(x-2)=0
x-2=0 move the two on the other side to get positive
x=2
(x-3)=0
x-3=0 move the three on the other side to get positive
x=3
75+150=225 in^2
Separate each layer.
Area1+Area2= Total area
A1= a*b*d
A2=a*c*d
A1=5*5*3=75 in^2
A2=5*10*3=150 in^2
