Answer:
D. 2
Step-by-step explanation:
So you use the formula with is 
. so you get (1 - -5)/(4-1). this gets you to 6/3 and you get 2
Angle 1 is a right angle, so therefore:
3y-6 = 90
3y = 96
Y = 32
I hope this Helps!
Answer:
3(n+7)-6=2n+10+n
Step-by-step explanation:
For discontinuity of the function:
x² - 7 x - 8 ≠ 0
x² - 8 x + x - 8 = 0
x ( x - 8 ) + ( x - 8 ) ≠ 0
( x - 8 ) ( x + 1 ) ≠ 0
The points of discontinuity are: x = - 1 and x = 8.
As for the Domain of the function:
x ∈ ( - ∞, - 1 ) ∪ ( - 1 , 8 ) ∪ ( 8, +∞ ).
7 x 3 = 21 so it is 21 ft cm your welcome
