I’m not sure sorry also it past due
Answer is 1, my mobile is not good but
Actually, you have to find four missed terms of geometrical sequence. Denote
and r - ratio, then
.
Since
, you have that
, then
.
Now substitude r=2 in each of unknown 4 terms:
.
Answer: four geometric means between 25 and 800 are 50, 100, 200, 400.
DEF= 6 ft^2
A= 1/2*b*h
Plug in what you know.
6= 1/2*4*h
Multiply like terms.
6=2*h
Divide 2 on both sides.
3=h
If the base of ABC= 12
12/4=3
3*3=9
A= 1/2*b*h
A= 1/2*12*9
A= 1/2*84
A= 42
The area of ABC is 42 ft^2
I hope this helps!

Step-by-step explanation:
Q3.
If ΔGHI and ΔJKL are similar, then the sides are in proportion:

We have
JL = x, GI = 9 ft, LK = 24 ft, IH = 12 ft.
Substitute:

<em> multiply both sides by 2</em>

Q4.
We must multiply the original length by a scale factor of 3/4:
