The expression foiled together is 6(-3x^2+13xy-4y^2)
Answer:
cos theta = 4/5
Step-by-step explanation:
Since this is a right triangle
Cos theta = opp side/ hypotenuse
Cos theta = 8/10
cos theta = 4/5
Answer:
the correct answer is -5 since y=7
So we know that:
3(-8 + 4v) = 8v
To find v, first simplify the left hand side:
-24 + 12v = 8v
Then group the "v's" over to the right:
-24 = -4v
-6 = -v
So v = 6
Hope this helped
18 + 18h = 180, subtract 18 from 180, then divide by 18 and that should give you 9.
9 = h
