Answer:
Step-by-step explanation:
You have to use the triangle inequality theorem:
12cm, 4cm, xcm
x > 4cm - 12cm
x > -8cm
x < 12cm - 4cm
x < 8cm
-8cm < x < 8cm
Answer:
It's a.
Step-by-step explanation:
(a - 2b)^2 + 8ab
= a^2 - 4ab + 4b^2 + 8ab
= a^2 + 4ab + 4b^2.
((a + 2b)^2 = a^2 + 4ab + 4b^2.

What are you supposed to do
Step-by-step explanation:
8. Similar parts


Choice a
9. The Law of Sines says a:b:c and
are the same ratio.
The sines will go in order for acute angles, we have to convert 120 to its supplement 60 and then the order is 29,31,"60" or opposite sides JK, KL, JL
choice b
10.
DEF and FEG are supplments, FEG=180-DEF=180-114=66
DEF and HEG are opposite angles, so congruent HEG=DEF=114

Answer:
5 cars
Step-by-step explanation:
If the average of cost of a car is $4,000 there will be enough cash to buy 5 cars. 20,000 divided by 4,000= 5.
