Add the length width and height all together
Answer:
First part: -10x-4y=-12
Second half: infinitely many solutions
Step-by-step explanation:
Just did the assignment and got it correct
Because if you multiply 2 different irrational numbers (like the following)

You will get an irrational answer.
BUT
if you multiply the same square root (which are both irrational, you get a rational number)
The lemght could be 15 because a triangle has two long sides and one short one and the two are equivalent
A = b*h*0.5
24 = 4*0.5*h
24 = 2*h
h = 12
Height is 12 inches.
