A square has all of the same sides, so just do 12x12 which is 144
Answer:
Dulcina's collection has 57 pins
Eva's collection has 25 pins
Step-by-step explanation:
first we are going to represent the relation of pins by means of an equation
d = Dulcina
e = Eva
e + d = 82
and now we represent the relation of the collections of each one
d = e + 32
having the 2 equations we can replace the d by (e + 32) and place it in the other equation
e + d = 82
e + (e + 32) = 82
2e + 32 = 82
2e = 82 - 32
2e = 50
e = 25
Now we replace e with 25 in the second equation and get the value of d
d = e + 32
d = 25 + 32
d = 57

Step-by-step explanation:
Answer:
non-linear
Step-by-step explanation:
Linear functions can only have powers of 1 for the x and y terms and the terms must not be multiplied.
The function y =2x^2-4 has a power of 2 on the x so it is not linear. It is parabolic.
