Area of trapezoid : (Base 1 + base 2) x h x 1/2
Let's solve!
( 2+6) x 5 X1/2
= 40x1/2
=20
20 in squared is the area!
(2x-5y)+(x+y)=(2x+x)+(-5y+y)=3x-4y.
therefore:
(2x-5y)+(x+y)=3x-4y
If a number equals the same number, there are infinite solutions
Example: 5=5, which is true, so there are infinite solutions
If a number equals a different number, there are no solutions
Example: 5=2, which isn’t true
Answer:
