Answer:it B I think
Step-by-step explanation:
I’m not sure though.
D'ou know the area of a circle?
In the standard form of quadratic
the discriminant is
In your quadratic, a = 1, b = -9 and c = -10
Now you need to plug these values into the expression for the discriminant.
Answer:
Step-by-step explanation:
Linear pairs
(4x + 1) + 75 = 180
Add the like terms
4x + 76 = 180
Subtract 76 from both sides,
4x = 180- 76
4x = 104
Divide both sides by 4
x = 104/4
x = 26
Area = Length * Width
A = (2x - 4) * (x + 5)
A = 2x² +10x-4x - 20
A = 2x² + 6x - 20
In short, Your Answer would be Option C
Hope this helps!
