Y(y+21) If you think about it you will see that it would most likely be this answer because the product of something is multiplying, and the sum is adding. If this answer is not correct then I am sorry.
        
             
        
        
        
Step-by-step explanation:
The distance formula between two points:

Substitute the coordinates of the points.

If a ≤ b < c are the sides of the right triangle, then
a² + b² = c²

used  for a ≥ 0.
 for a ≥ 0.
 therefore ΔABC is a right triangle.
 therefore ΔABC is a right triangle.
 
        
             
        
        
        
Answer:
Hey there! ok , so your equation would be 28 / 3
Step-by-step explanation:
The equation would be 28/3 because there are 28 students in the class and the ratio of boys to girls is 3-9 meaning that it is 1/3, which is the same as dividing by 3, so the equation would be 28/3
 
        
             
        
        
        
X+y=27
x=2y
2y+y=27
y=9
x=27-y
x=27-9=18
        
             
        
        
        
First calculate total payments
18×95.25=1,714.5
After that to find the interest you just subtract the amount borrowed from the total payments
Interest=1,714.5−1,450=264.5
Hope it helps!
