Answer:
(A) -2
Step-by-step explanation:
19y-9 is a simpler form of this expression. You can use distributive property to get rigid the brackets (multiply -3 by -4y and 3) , then your expression looks like 12y-9+7y. You then combine like terms to get 19y-9.
Answer: 2(2x+3)/(x+1)(x+2)
Answer:
T = 60 degrees
Step-by-step explanation:
The dotted line is the height so it is a right angle
We are able to use trig functions since this is a right triangle
cos T = adj side / hyp
cos T = a/b
cos T = 8 sqrt(2) / 16 sqrt(2)
cos T = 1/2
Taking the inverse of each side
cos^-1 ( cosT) = cos^-1 ( 1/2)
T = 60 degrees
Answer: (f + 2) (f + 8)
It's hard to explain, but I suggest you use the AC method. Hope this helps!
