D because the parallel sides are both considered bases
To simplify 2x+3-x+5, we can first group x together,then calculate:

Therefore the answer is x-2.
Hope it helps!
Answer:
a) 40 sides
b) 6840
c) 9 gegrees
Step-by-step explanation:
interior angle= (<u>n</u><u>-</u><u>2</u><u>)</u><u>1</u><u>8</u><u>0</u>
n

so total number of sides is 40
b) Sum of interior angles= (n-2)×180
(40-2)×180
38×180
6840
c) Exterior angle = 360 ÷ n
360÷40 =9 degree
Answer:
a=4
Step-by-step explanation:
5a-8=8+a
4a-8=8
4a=16
a=4
