Answer:
(x-10) (x+1) =0
x=10 x=-1
Step-by-step explanation:
x^2 -9x-10 =0
Factor
What two numbers multiply to -10 and add to -9
-10*1 = -10
-10+1=-9
(x-10) (x+1) =0
Using the zero product property
x-10 = 0 x+1=0
x-10+10=0+10 x+1-1=0-1
x=10 x=-1
These are the x intercepts

21 ÷ 12 = 1.75
Answer:
7,2,3
Step-by-step explanation:
Congruent angles means that both angles have same measure.
Remember that if both lines cross-intersect each others, both form same measure.
Therefore:-
angle 6 = angle 7
Assume that both lines are parallel, we can say that angle 6 = angle 2
Since angle 6 = angle 2 and angle 2 = angle 3 via cross-intersect, that means angle 6 = angle 3 as well. angle 6 = angle 3 is alternate interior angle theorem.
Thus:- angle 7, 2 and 3 both are congruent
