Answer:
18
Step-by-step explanation:
I'm not sure but there is a rule that the sum of out side angles of each shape is 360
saying that 360/5= 72
so if we continue the lines it will be 36 degree to of the outside angles and 18 degree each
Not let's make that into another rectangle (The one that is upside down)
180- (2*18)= 144
So the big degree is 144
now again
(180-144)/2=18
So each of those small red angles are 18
Answer:
$23.32
Step-by-step explanation:
To factor x²-2x-4, you are looking to answer three questions.
1) What pair of numbers multiplies to 4?
2) What pair of numbers multiplies to 1?
3) Do these pairs when multiplied together, add/subtract to the middle term?
To answer (1), our pairs are 2 and 2, 4 and 1. Since there's a negative with 4 at the end (from question one), the signs will be opposite.
To answer (2), only pair multiplies to 1 - 1 and 1. Let's try both pairs from 1.
(x-4)(x+1) The middle term here is -3x. Nope.
(x-1)(x+4). The middle term here is 3x. Nope.
(x-2)(x+2) The middle term is 0x (or no middle term). Nope.
So x²-2x-4 does not factor.
Answer:
-4(8)=x^2-9x+12
-32=x^2-9x+12
