Find the perimeter of a rectangle with a length of 6x+3 and a width of -2x-5.

Answers

Answer 1
The simple way of calculating a perimeter is to add all of the sides.
For a rectangle this would equal 2 x length + 2 x width
P = 2(6x + 3) + 2(-2x - 5)
= 12x + 6 - 4x - 10
= 8x - 4

At a higher level both the length and width must be greater than zero (= zero is a trivial rectangle)
6x + 3 > 0
6x > -3
x > -0.5

-2x - 5 > 0
2x + 5 < 0 (multiplying by -1 reverses the inequality)
2x < -5
x < -2.5

This rectangle cannot exist as x cannot be < -2.5 and > -0.5 at the same time!
Answer 2

L=6x+3

B=-2x-5

[tex]\\ \rm\longmapsto Perimeter=2(L+B)[/tex]

[tex]\\ \rm\longmapsto Perimeter=2(6x+3-2x-5)[/tex]

[tex]\begin{gathered}\\ \rm\longmapsto Perimeter=2(4x-2)\end{gathered}\begin{gathered}\\ \rm\longmapsto Perimeter= 8x-4\end{gathered}[/tex]

A missile was fired from a submarine from 220 feet below sea level. If the missile reached a height of 10400 feet before exploding, what was the change in the altitude of the missile?

Answers

Answer:

10,620

Step-by-step explanation:

Since it reached a height of 10,400 before exploding and was 220 feet below sea level we need to add the two numbers together to get the total change in altitude.

You can think of it as sea level = 0 so 220 feet below sea level is -220 and 10,400 above sea level is +10,400 so what's the difference between the two.

Finding the Difference

10400 - (-220)

=  10400 + 220

=  10620

Convert to actual scale based on proportion of 1:30

4.5 x 30 = 135 inches

2 x 30 = 60 inches

135 x 60 = 8100 inches^2 though we need this in feet and because we solved for area we need to divide by 12in^2*12in*^2

8100/144 = 56.25 or roughly 56 ft^2

Answers

Answer:

  y -2 = 1/4(x +3)

Step-by-step explanation:

Process: find the negative reciprocal of the slope of the line shown and put the appropriate values into the point-slope equation.

__

The slope of the given line can be found as the ratio of rise to run between the marked points.

  m = rise/run = -8/2 = -4 . . . . counting grid squares

The desired line has a slope that is the opposite reciprocal of this:

  m' = -1/m = -1/-4 = 1/4

The point-slope equation of a line with slope m through point (h, k) is ...

  y -k = m(x -h)

Then the desired line with slope 1/4 through point (-3, 2) has equation ...

  y -2 = 1/4(x +3)

To pay for a 15,300 car, Tony made a down payment of $3900 and took out a loan for the rest. On the loan , he paid monthly payment payment of $252.34 for 4 years.

Answers

Answer:

a. $24,512.32

b. $712.32

Step-by-step explanation:

a. A price of car $15,300, Tony made a down payment of $3900 so car has $11,400 left of a price and took out a loan.

He paid monthly payments of $252.34 for 4 years. Which mean $252.34 is paid for 48 months, multiplication $252.34 and 48 are $12,112.32. So we have monthly payments is $12,112.32

The total amount Tony ended up for the car is $11,400 + $12,112.32 = $24,512.32

b. The interest Tony pay on the loan is $12,112.32 - $11,400 = $712.32

In this situation, you have:
The mode is 79 (that’s the most common number).

The mean is less than both of those, as it was brought down by the few scores of 49.

The means the mean will be less than median.
