Answer:</h2>
<h2>
Step-by-step explanation:</h2>
A trapezoid is a quadrilateral where at least one pair of opposite sides are parallel. In a trapezoid, the both parallel sides are known as the bases of the trapezoid. So we have two bases, namely, 
. Also, the height 
of the trapezoid is the length between these two bases that's perpendicular to both sides. So the area of a trapezoid in terms of of 
is:
Since:
The area is:
Arithmetic sequences have a common difference between consecutive terms.
Geometric sequences have a common ratio between consecutive terms.
Let's compute the differences and ratios between consecutive terms:
Differences:
Ratios:
So, as you can see, the differences between consecutive terms are constant, whereas ratios vary.
So, this is an arithmetic sequence.
Answer:
x=-2.5
Step-by-step explanation:
4x+(7-3)5=10
4x+(4)5=10
4x+20=10
subtract 20 from each side
4x=-10
divide each side by 4
x=-2.5
Answer:
its 16m+2
Step-by-step explanation:
you add m and 15 m because they have the same variable.
then you put the two right next to it
