Answer:
∠ LMP = 77° , ∠ NMP = 103°
Step-by-step explanation:
The 2 angles on the straight line sum to 180° , that is
∠ LMP + ∠ NMP = 180 , substitute values
- 16x + 13 - 20x + 23 = 180 , that is
- 36x + 36 = 180 ( subtract 36 from both sides )
- 36x = 144 ( divide both sides by - 36 )
x = - 4
Then
∠ LMP = - 16x + 13 = - 16(- 4) + 13 = 64 + 13 = 77°
∠ NMP = - 20x + 23 = - 20(- 4) + 23 = 80 + 23 = 103°
Answer:
d = Sqrt 41 = 6.4
Step-by-step explanation:
d = sqrt [(x-x)^2 + (y-y)^2]
d = sqrt [(-7 - - 2)^2 + (7-3)^2]
d = sqrt[(-7+2)^2 + (4)^2]
d = sqrt [(-5)^2 + (4)^2]
d= sqrt (25 + 16)
d = sqrt 41 = 6.4
Answer:
(x+1)(x+8)
Step-by-step explanation:
x^2+9x+8
You just need to multiply the first number to the last. (a·c) In this case *a* is jus a positive 1. Then, you just find a product to the result you got from (a·c) that when it is added together the result is the same as the one you have as ¨b¨.
Also the sign betwee b and c tells you that if it is positive both of your products are going to have the same sign, and if it is negative it means that they are going to be different,(one negative and one positive). If the sign is positive then go to the sign between a and b, this tells you what sign your factors will have.
<h2>x^2+9x+8</h2>
a·c=8
<u>Product Sum</u>
1,8 8
2,4 6
ect... ect...
x^2+x+8x+8
x(x+1) 8(x+1)
(x+1)(x+8)
