Hello,

A:
2x²-7x-4=0
==>2x²-8x+x-4=0
==>2x(x-4)+1(x-4)=0
==>(x-4)(2x+1)=0
==>(x=4) or (x=-1/2)

A bicycle wheel travels 30π inches for each revolution. What is the diameter of the wheel?15π in

30 in

15 in

30π om

Answers

The distance traveled is given by:

$S = R \alpha$

Where,

R: bicycle wheel radio

α: central angle

The angle for a revolution is:

$1rev = 2 \pi rad$

Therefore, substituting values we have:

$30\pi = R (2\pi)$

Clearing the radio we have:

$R = (30\pi)/(2\pi)$

$R = 15$

Then, the diameter is given by:

$d = 2R$

$d = 2 (15)$

$d = 30$

Answer:

the diameter of the wheel is:

$d = 30in$

Final answer:

The circumference of a bicycle wheel traveling 30π inches in a revolution is equivalent to 30π. Using the circumference formula of a circle, C = πd, where C is the circumference and d is the diameter, we find that the diameter of the wheel is 30 inches.

Explanation:

The question is asking for the diameter of the bicycle wheel which travels 30π inches for each revolution. In other words, the distance that it travels in one full revolution is equivalent to the circumference of the wheel. The formula of the circumference of a circle (or wheel in this case) is C = πd, where C is the circumference and d is the diameter.

So if we plug our values into the formula, we get 30π = πd. Solving this equation for d (diameter), we simply divide each side by π. The π on the right side cancels out and on the left side the π in 30π also cancels out. The diameter of the wheel is therefore 30 inches.

How do I factor x^2+7×+6

Answers

$x^2+7x+6\n\n7x=6x+1x\n\n6=6\cdot1\n\nx^2+7x+6=(x+6)(x+1)$

To factor the equation, you need to convert it to the form (x+a)(x+b) and find out what a and b are.
When you multiply (x+a)(x+b), you get x² + (a+b)x + ab.
With the expression x² + 7x + 6, we know that a+b is equal to 7 and a times b is equal to 6.
The only two numbers that add to 7 and multiply to 6 are 1 and 6, leaving us with:
(x+6)(x+1)
