Answer:
4
Step-by-step explanation:
a scale factor means how much something changes in length, area, or volume. it is somewhat like a multiplier. EF is 12 units long but E'F' is 3 so 12 ÷ 3 = a scale factor of 4
X=larger number
y=smaller number
3x = 4y
x+y=21
3x=4y
3x÷3= 4y÷3
x = 4/3y
x+y=21
4/3y+y=21
1 4/3y=21
1 4/3y ÷ 1 4/3=21 ÷ 1 4/3
y = 9
x+ y = 21
x + 9 = 21
x + 9 - 9 = 21-9
x = 12
Check
3x =4y
3(12) = 4(9)
36=36
