Answer:
Exactly two distinct zeros
Step-by-step explanation:
y = 2(x-1) (x + 4)
Plug y = 0
0 = 2(x-1) (x + 4)
0/2 = (x-1) (x + 4)
(x-1) (x + 4) = 0
(x-1) = 0 or (x + 4)= 0
x = 1 or x = - 4
Here, x has two distinct roots, therefore given quadratic relation has Exactly two distinct zeros.
You would do (2x+60)+6x=180... when you simplify you get 15.

Step-by-step explanation:
Given:
Diameter of each doughnut = 8 cm
To find: circumference of each doughnut
Solution:
Circumference refers to the boundary of a geometric figure.
A doughnut has the shape of a circle.
Let r represents the radius of the circle.
Diameter of each doughnut = 8 cm
Radius of each doughnut (r) = Diameter/2

Circumference of each doughnut 
Put 
So, circumference = 

Answer:
B 9.72
Step-by-step explanation:
If we imagine 7.48 is 100% Then we can use multiply and divide to find 30%. It goes like this. x/7.48 = 30/100. Where x is the unknown. Take 30 times 7.48 which is 224.4 then divide by 100 we get 2.24 dollars. Added to 7.48 we get 9.72
