Answer:
This is simple. The answer is 60 for the first, and the second one I believe is 85
Step-by-step explanation:
Since we are dealing with quadrilaterals, we know that all the inside angles add up to 360. In your isosceles trap. the top two angles are the same, and the bottom two are the same. So, we can do 120*2=240 for the top angles, and then subtract that from 360. 360-240=120. 120/2=60

6a-2(a-1)
6a-2a-2
4a-2
I think it is 4a-2
A square has 4 equall side so if one side is 2x+3
then:
the perimeter is 2x+3 + 2x+3 + 2x+3 + 2x+3
Combine like terms and the answer is:
8x+12
The equivalent expressions are: A and C
Answer:
divided by 6
Step-by-step explanation:
Given pattern
360,60,10
would it be add 60
lets
add 60 to each term
360 +60 = 420
but next term is 60, hence it incorrect choice
divided by 6
lets divide each term by 6
360/6 = 60 which is the next term in the series as well
60/6 = 10 which is also the next term in the series as well
hence divided by 6 is the correct option.
multiply by 6
multiply by 6 to each term
360 *60 = 21600
but next term is 60, hence it incorrect choice
subtract 60 from each term
360 -300 = 60 which is the next term in the series
60 -300 = -240 which is not same the next term in the series that is 10
hence this is incorrect choice
