Answer:
The correct answer would be 2π x 2²/5
Step-by-step explanation:
First, calculate the product, and evaluate the power which would be 2³π/5 and the solution is in an alternate form, therefore making it rational. :)
It would be C and here's why:
you originally start with 3x² - 14x - 5. The AC method to factoring says you have to get two middle terms that multiply to whatever 3 × -5 is and have to add to -14. Well 3 × -5 is -15. Raul chose two middle terms of 15x and -1x and 15 × -1 is -15 so that part is correct. However 15 - 1 = 14. The middle term of our original trinomial is -14 so "<span>The two middle coefficients multiply to the correct number, but do not add to the correct number."</span>

Answer:
x = 125°
Step-by-step explanation:
There are 7 angles in this shape. The sum of the angles in a shape like this is calculated using a formula.
Total of angles
= (n - 2)•180°
Put in 7, because there are 7 angles.
= (7 - 2)•180°
= 5•180°
= 900°
So the total of the angles should be 900°. We know all of the angles except one.
900° = 123°+129°+128°+128°+132°+135°+ x
900° = 775° + x
Subtract 775.
125° = x
The missing angle is 125°.
