Multiple Choice The perimeter of a square

Mathematics
1 answer:
Oduvanchick [21]3 years ago
5 0

Answer:

The answer is B, 5.

Step-by-step explanation:

3x+2 is per side. A square has 4 sides. 3x+2 times 4 is 12x+8 (using the distributive property).

12x+8 = 68

12x = 60

divide both sides by 12...

60/12 = 5.

Therefore x =5

True or False? Two arcs of a circle are congruent if and only if their associated radii are congruent.
Nataliya [291]

The <em>correct answer</em> is:


False.


Explanation:


Two arcs are congruent if and only if their associated <em>chords</em> are congruent.


The associated radii of arcs are the radii of the circles the arcs are in. However, you can have two arcs in one circle that are not congruent. The circle would not have two different radii, but the arcs would not necessarily be congruent.

Please can anyone help me
Inga [223]

Answer:

f(x) = 0.5x + 15

Step-by-step explanation:

Here, we want to get the total charge

From the question;

we have a flat rate of $15

now, $0.5 per mile for x miles will be a charge of 0.5 * x = $0.5x

We now add this to the flat fee to get the total score

That will be;

f(x) = 15 + 0.5x
