A, B, and D. A trapezoid cannot be parallel because the 2 left and right sides will eventually meet/connect.
The answer is 1,000. 500(2)= 1000
Let us take the second equation first
2a + 2b = 6
Dividing both sides by 2 we get
a + b = 3
a = 3 - b
Putting the value of a in the first equation we get
3a + 4b = 9
3(3 - b) + 4b = 9
9 - 3b + 4b = 9
b = 9 - 9
= 0
Now putting the value of b in the second equation we get
a + b = 3
a + 0 = 3
a = 3
So the value of the unknown variable a is 3 and the value of the unknown variable b is 0.
14, 16, 17, 19, 20
17 is the middle one so the answer is 17
Hope this helps :)
Answer:
g = -2
Step-by-step explanation:
6=g+8
Subtract 8 from each side
6-8=g+8-8
-2 =g
