Answer:
64 : 343
Step-by-step explanation:
When working with scale factors
Lengths are related by the scale factor
perimeters are related by the scale factor
areas are related by the scale factor squared
volumes are related by the scale factor cubed
The scale factor is 4:7
The volumes are related by 4^3 : 7^3
64 : 343
35 + 35 =70 i guess its saying to add up the months so i guess its saying whats 35 + 35 =70 thats what i got
Add 25 to both sides x-25 +25 =7 +25
x =32
ANSWER

EXPLANATION
The quadratic equation is:

Group variable terms:

Add the square of half, the coefficient of y to both sides.


The LHS us now a perfect square trinomial:

Take square root:


The first choice is correct.
3x+4x+5x=54
12x=54
x=4.5
Plug in the value of x into all three segments.
AB= 3*4.5= 13.5
BC= 4*4.5= 18
AC= 5*4.5= 22.5
