3(x+2)^2=48 with word steps

lesya692 [45]

Answer:

Divide both sides by 3.

(x+2)^2=16

Square root both sides.

x+2= ± 4 (plus OR minus, can be either so we have to include both)

Minus 2 from both sides.

x=-2 ± 4

Add and minus the 4 to -2.

x = -2-4 = -6 and x=-2+4 = 2

Carl is wondering if the train he is riding home from school will leave early, on time, or late. The probabilities are as follow

Slav-nsk [51]

Answer:

Probability of each situation is 1/3 .

Step-by-step explanation:

There are 3 possibilities

1- Train will arrive early

2- Train will arrive on time

3- Train will arrive late

Formula for Probability of event a is = n(a)/Sum of events

In this case sum of events = 3

Probability of early arrival = 1/3

Probability of on time arrival = 1/3

Probability of late arrival = 1/3

For each hour he babysits, Anderson earns $1 more than half of Carey's hourly rate. Anderson earns $6 per hour. Which equation c

MAVERICK [17]

Answer:

The total earnings of Carey in t tours is 12 t - 2 .

Step-by-step explanation:

For each hour he babysits, Anderson earns $1 more than half of Carey's hourly rate. Anderson earns $6 per hour. Which equation can be used to solve for Carey's hourly rate, c? 18 + ?T = 24 What number should be the coefficient of t?

Anderson earns $1 more than half of Carey's hourly rate.

Anderson hourly rate = $ 6

Let Carey's hourly rate is p. Let the time is t hours.

So, Anderson rate is

$6 t = \frac{p t}{2} +1\\\\2\times 6 t = p t + 2 \\\\p t = 12 t - 2$

Please I need this before 12pm

Answer:

The required formula is:

$\ a_{n}=a_{1}+(n-1)d$

Step-by-step explanation:

The total number of squares of the the first term = 4

The total number of squares of the the second term = 7

The total number of squares of the the third term = 10

so,

$a_1=4$

$a_2=7$

$a_3=10$

Finding the common difference d

$d=a_3-a_2=10-7=3$

$d=a_2-a_1=7-4=3$

As the common difference 'd' is same, it means the sequence is in arithmetic.

If the initial term of an arithmetic progression is $a_{1}$ and the common difference of successive members is d, then the nth term of the sequence $(a_n)$ is given by:

$\ a_{n}=a_{1}+(n-1)d$

Therefore, the required formula is:

$\ a_{n}=a_{1}+(n-1)d$
