Answer:

your answer is correct

Step-by-step explanation:

4b² + 8b + 3

Consider the factors of the product of the coefficient of the b² term and the constant term which sum to give the coefficient of the b- term.

product = 4 × 3 = 12 and sum = + 8

The factors are 2 and 6

Use these factors to split the b- term

4b² + 2b + 6b + 3 ( factor the first/second and third/fourth terms )

= 2b(2b + 1) + 3(2b + 1) ← factor out (2b + 1) from each term

= (2b + 1)(2b + 3)

solving a linear equation we conclude that the value of x must be 6.

<h3>How to find the value of x?</h3>

On the statement we have the relations:

AB = BC

BC = CD

For the transitive property, then we have that:

AB = CD

Replacing the equations in the image, we get:

2x + 1 = 4x - 11

Solving this linear equation for x we get:

1 + 11 = 4x - 2x

12 = 2x

12/2 = x

6 = x

So yes, solving that linear equation we conclude that the value of x must be 6.

A car is driving at 65 kilometers per hour. How far, in meters, does it travel in 3 seconds?
kati45 [8]

Step-by-step explanation:

65 km / h = 65,000 m / 3600 s

what do we need to multiply 3600 with to get 3 ?

3600 × f = 3

f = 3/3600 = 1/1200

now, we need to multiply 65,000 by the same factor to get how many meters the car is driving in these 3 seconds :

65000 × 1/1200 = 65000/1200 = 54.16666666...

so, rounded, it travels 54 meters in 3 seconds.
