How do I find a change in scale factors? I forgot to write notes on how to find a change in scale factors and can’t seem to find

a video. A formula and/or explanation would be absolutely wonderful! Or, a video recommendation from someone who explains it would do as well. :) This is for a seventh-grade level question.

Answer:

In two similar geometric figures, the ratio of their corresponding sides is called the scale factor.

To find the scale factor,we need to follow some rules:

locate two corresponding sides, one on each figure.

Write the ratio of one length to the other to find the scale factor from one figure to the other

Point h is between g and i. If gh = 2x2 + 7x, hi = 9x – 2, and gi = 38, find the length of gh, hi and the possible values of x.
yuradex [85]
2x²+7x+9x-2=38
2x²+16x-40=0
2(x²+8x-20)=0
2(x+10)(x-2)=0
x=-10 or x=2
if we let x=-10 we get negative lengths for some of the segments which is not allowed so discard it. for x=2,

gh=22, hi=16, and gi=38

Two toy rockets are launched straight up into the air. The height, in feet, of each rocket at t seconds after launch is given by
Tema [17]

Given:

The height, in feet, of each rocket at t seconds after launch is given by the polynomial equations:

Rocket A: -15t^2+100t

Rocket B: -14t^2+85t+3

To find:

The equation to find the "difference" in height of Rocket A and Rocket B.

Solution:

The difference in height of Rocket A and Rocket B is:

Difference = Height of Rocket A - Height of Rocket B

\text{Difference}=(-15t^2+100t)-(-14t^2+85t+3)

\text{Difference}=-15t^2+100t+14t^2-85t-3

\text{Difference}=(-15t^2+14t^2)+(100t-85t)-3

\text{Difference}=-t^2+15t-3

Therefore, the difference in height of Rocket A and Rocket B is -t^2+15t-3.
