Equation: 3(x+4)=3x+11

Can be simplified using distribution of parentheses: 3x+12=3x+11

Now we subtract 3x from both sides and get: 12=11

Which is false (12\neq11) and therefore the equation has no solution x=\emptyset

Feel free to ask anything ;)

<h3>Answer</h3>

3 \times (x + 4) = 3x + 11

3x + 12 = 3x + 11

That's impossible, cause 3x plus 12 can't be equal to 3x plus 11.

the smith family is designing new plans for an in ground pool. mr smith draws a rectangular shape with a length that is 5 feet l
Mnenie [13.5K]
Answer:
area of pool = w(w+5) = w^2 + 5w square feet

Explanation:
The height of the pool is used as its width.
Assume that the width of the pool is w feet.
Now, we are given that the length of the pool is 5 feet longer than its width.
This means that:
length of the pool = w + 5 feet
The area of the rectangle is calculated as follows:
area = length * width
area = (w+5) * (w)
area = w^2 + 5w square feet

Hope this helps :)

Assume that the random variable X is normally distributed, with mean ? = 50 and standard deviation ? = 7. Compute the following
sineoko [7]

Answer:

Step-by-step explanation:

Given that  the random variable X is normally distributed, with

mean  = 50 and standard deviation  = 7.

Then we have z= \frac{x-50}{7} is N(0,1)

Using this and normal table we find that

a) P(56

b) When z=0.02

we get

x=50+0.02(7)=50.14

c) 90th percentile z value =1.645

90th percentile of X =50+7(1.645)\\= 50+11.515\\=61.515
