There are 440 boys and 460 girls
The answer for that is the second one
Dilation with scale factor of 3= E.
translation 3 units up= D.
translation 3 units right= B.
horizontal stretch by a factor of 3= A.
vertical stretch by a factor of 3= C.
translation= its move places, so you are adding
stretch= it changes shape. you can either stretch it horizontally or vertically so you are multiplying
going up and down/ vertically is the y-axis

hope this helped!
Answer:y= -5x+1
9=-5(-2)-1=9
-4=-5(-1)-1
Step-by-step explanation:
Length = x + y
Area of a square = Length x Length
The expression can be :
1) Area of the square = (x + y)(x + y)
2) Area of the square = (x + y)²
3) Area of the square = x² + 2xy + y²
