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:
1.5 cookies and 0.5 brownies are needed for 1 plate. In 10 plates, you will need 15 cookies and 5 brownies.
To answer equation there is only one solution which is, x=12
Answer:
x=8
Step-by-step explanation:
2*3x=6x
2*-7=-14
6x-14=34
6x+14=34+14
6x=48
6x/48
x=8
The answer is -34 cause if x is -7 and y is 3 then you know you switch em out and do the thing and get the answer.
