Answer:
B, because it's pretty much 3+ and 3- so in result 0
Okay first set up the equation
x
--- -2 = 5.5
-3
add over the 2
x
--- = 7.5
-3
now you need to multiply the denominator by the answer
(-3)(7.5) = x
-22.5 = x
2(x-1)=42
2x-2=42
2x=44
X=22
False.
The scale factor for 3 and 45 is 15.
45 / 3 = 15.
We know that 25 isn't even a whole number for the scale factor, because no number x 4 can equal 25 (whole numbers only).
25 / 3 = 6.33333

solve for "b", to see what the base is
what about the height? well, h = 4b
