Answer:
C. 15
Step-by-step explanation:
Small triangle is similar to larger one so we can use the similarity ratio to solve the question:
CE/CA = DE/AB
4/12 = 5/AB cross multiply expressions
4AB = 60 divide both sides by 4
AB = 15

i am not 100% but like i looked up examples and that seems to be the only one that looks right
Answer:
345(I think)
Step-by-step explanation:
So I'm guessing that the x2 is your way of saying 2 is the exponent right? In that case the equation would be 8x^2 + 12x
Well you would have to pull out the gcf which in this case will be 4x after pulling out the gcf you should get 4x(2x + 3)
82/4+20-15
82:4=20.5
20.5+20=40.5
40.5-15=25.5
