Answer:
are zeroes of given quadratic equation.
Step-by-step explanation:
We have been a quadratic equation:

We need to find the zeroes of quadratic equation
We have a formula to find zeroes of a quadratic equation:

General form of quadratic equation is 
On comparing general equation with b given equation we get
a=2,b=-10,c=-3
On substituting the values in formula we get


Now substituting D in
we get




Therefore,

Answer:
2(4x-6)
4(2x-3)
8(x-3/2)
Step-by-step explanation:
find all factors of 8 other than 1, you should have 3
divide the whole equation by the factor then multiply by the factor
2(8x-12)/2 = 2(4x-6)
4(2x-3)
8(x-3/2)

Answer:
14. C) 136°
15. C) 40°
Step-by-step explanation:
Inscribed angles are half the measure of the arc they intercept. For an inscribed quadrilateral, this means opposite angles are supplementary.
__
14) ∠H +∠W = 180°
34x +55x +2 = 180
89x = 178 . . . . . . . . . subtract 2
x = 2 . . . . . . . . . . . . . divide by 89
arc VX = 2(34x) = 68(2) = 136 . . . degrees
__
15) The sum of angles in the triangle is 180°.
? + 80° + (120°/2) = 180°
? = 40° . . . . . . . . . . subtract 140°
Answer:
80 in.
