Mashutka [201]3 years ago
6 0

Answer:

for the first 2 neither one is a polygon because a polygon has straight sides and is closed connections were the first shape has an open connection and the second shape has a curved line. for question i believe is 48 and question 4 is 145.

explanation.

for the last 2 problems their total equal 360 so you just add up all the side then subtract the number you got by 360 and that's your answer. ex.) 120 +130+ 62=312. 360-312=48

8. Solve the system of equations using substitution.
Elodia [21]

Answer:

D

Step-by-step explanation:

In order to solve this we need to plug in the answer choices and make sure they work for BOTH answers!

Let us start with option A. (6,3)  3 = 4(6) + 6     = 3 = 30 This is automaticly wrong because 3 doesnt equal 30. There is no need to try it on the second equation since the first one was wrong.

Next answer choice, B  (3,6)  6 = 2(3) =   6=6. The second equation works perfect for this. Now we have to make sure that it works for the first one as well. 6 = 4(3) + 6   = 6 = 18 which is wrong.

Next, C.  (1,2)   2 = 2(1) = 2=2 Right now lets check the other equation.

2 = 4(1) + 6 = 2=10. Wrong

Last, D. (-3, -6)    -6 = 2(-3)  = -6 = -6 Right now lets check the other equation.

-6 = 4(-3) + 6 = -6 = -6. CORRECT. Answer choice D works for both equations.

Sorry for the wait of response.

Hi! Got a question!!
Rasek [7]

To convert cm³ to m³, you can break down the units.

cm³ = cm x cm x cm

Each cm is converted to m so :

m³ = m x m x m

= 1/100 x 1/100 x 1/100

= 0.000001

So, 1cm³ is 0.000001m³, so to convert cm³ to m³ you divide your value by 1,000,000 and vice versa.

1. 0.35m³

2. 8m³

3. 43.34m³

4. 30m³

5. 0.77m³
