When you factor the equation...
r^2-4r-77
r^2+7r-11r-77
r(r+7)-11(r+7)
(r-11)(r+7) so each parenthetical term is a dimension.
Note that r>11 though for any possible real solution.
Answer:
D
Step-by-step explanation:
3 cards
1/4 = x/12 1/4 = 3/12
4 * 3 = 12
1 * 3 = 3
x = 3
Thats when point =0. equation of a line mx +b where m is the slope
and b is the intercept
