Answer:
4 solutions
Step-by-step explanation:
remember that y=mx+b
So 2/5x would be you m.And -3/7 is your b
Since the properties of a rhombus tells us that both pairs of opposite sides are congruent we can therefore conclude that DB will be 12
The answer is 20!
you need to change the subtraction sign to an addition sign and change -4 to a 4. then, solve!
hope this helps!!
