The best way to answer this is to find counterarguments for each answer to eliminate them as a possibility. ab doesn't have to be an integer, 2.5*3=7.5 . That's also not an imaginary number so that's out. And that's also not an irrational number so that's out too. Only choice left is rational number.
Answer:
Step-by-step explanation:
-7x-3=21 then 21x-1=-21
Area = length x width
With a square, all 4 sides are the same length. So, multiply.
A = 13 x 13
A = 169 yd sq
lets work on the triangle with 60 and 70.
they make 130, and a triangle has 180 degrees, so that angle is 50
50+95+? is 180?
its 35
35+75 si 110, 180-110
so 70.
