Answer: x = 1.32 and x= 0.076
Step-by-step explanation:
4x(5x-2) = 20x-2
20x^2-8x = 20x-2
20x^2-8x-20x+2=0
20x^2-28x+2=0
Using quadratic equation
x = (-b +or- √(b^2-4ac))/2a
a =20, b=28, c= 2
Substitute into the equation
x= (7+√39)/10. = 1.32
x = (7-√39)/10 = 0.076
Answer:
a) >
b) >
c) <
d) >
Step-by-step explanation:
a) -3 is closer to 0 so it is larger
b) A positive number is always larger than a negative
c) A positive number is always larger than a negative
d) -234 is 1 larger than -235 which makes it larger
Y = 168° [ Because opposite angles are equal ]
x = 5x - 48 [ Because opposite angles are equal ]
4x = 48
x = 12°
I think the answer is b
