Answer:
4:1
Step-by-step explanation:
If the side length x is dilated to 2x, the area x² will dilate to (2x)² = 4x², which is 4 times the original x².

Answer:
A. V(x)= (50-2x) ( 35-2x)x
Step-by-step explanation:
Answer:
c = -2
Step-by-step explanation:
4(3+c)+c=c+4 =
4(3+c)+c-c=c+4-c =
4(3+c)=4 =
[4(3+c)]/4=4/4 =
3+c=1 =
3+c-3=1-3 =
c = -2
So
if x is the number she spent on each sister and y is the number she spent on each nephew then
180=3x+2y
she wants to spend 15 dollars more on sisters than nephews
so
x=15+y
solve
we have
180=3x+2y and
x=15+y
subsitute 15+y for x
180=3(15+y)+2y
180=45+3y+2y
180=45+5y
minus 45 both sides
135=5y
divide both sides by 5
27=y
solve for x
x=15+y
x=15+27
x=42
she spent $42 on each sister
