Angle 5 is identical to Angle 2
so it would be 27 degrees
Answer:
b) 
Step-by-step explanation:
We can use the discriminant 
to determine how many real solutions a quadratic equation in the form 
has.
- discriminant > 0 ⇒ 2 real solutions
- discriminant = 0 ⇒ 1 real solution
- discriminant < 0 ⇒ no real solutions
Well it is distributive but you don't but the multiplication sign by the 8 with the parenthesis so it would be 8(12*5) and then you do 8*12 which is 96 and then 8*5 which is 40 and then add 96+40
Answer:
= 2x^4 + 6x^3 - 8x^2 + 24x
= 2x ( 2x^3 + 3x^2 - 4x + 12)
Step-by-step explanation:
(X^2 + x - 6) (2x^2 + 4x) =
Let's open the brackets carefully
x^2 * 2x^2 + x^2*4x + x*2x^2 + x*4x - 6*2x^2 - 24x
= 2x^4 + 4x^3 + 2x^3 + 4x^2 - 12x + 24x
= 2x^4 + 6x^3 - 8x^2 + 24x
= 2x ( 2x^3 + 3x^2 - 4x + 12)
