Answer:
x=2
x=-5
Step-by-step explanation:
You need to get everything on one side to have a quadratic equation:
x^2+6x-4 -(3x+6) = x^2+3x-10
All factors of 10 are 1*10 and 2*5.
5-2 = 3 and 5*-2 = -10
Factoring x^2+3x-10 gives us (x-2)(x+5)
x=2
x=-5
You just put them in paper and then write if it is liner number. hope it help
Answer:
B 2/5
F theoretical > experimental
Step-by-step explanation:
P(heads) = numbers of heads/ total
=8/20 = 2/5
The theoretical (1/2) is greater than the experimental probability
1/2 > 2/5
Answer:
x = 59°
Step-by-step explanation:
The angle marked 115° and the angle that is the sum of angles x and 56° are alternate interior angles, so have the same measure:
115° = x +56°
59° = x . . . . . . . subtract 56°
