Length of a rectangle is 3 times it’s width perimeter 48 find area

Mathematics
1 answer:
valkas [14]3 years ago
6 0

Answer:

Let width = l

Therefore, length = 3l

Perimeter = 2(l+b)

48 = 2(l+3l)

48 = 2× 4l

48 = 8l

8l = 48

l = 48/8

l = 6

Width = 6

Therefore, length = 3×6

= 18

Area = l×b

= 18×6

= 108

Which equation represents a nonlinear function?
Luden [163]
The correct answer is:  [A]:  " <span>x(y – 5) = 2 " .
</span>_____________________________________________________
Consider:
_____________________________________________________
Choice:  [A]:  " x(y–5) = 2 " ; 

Divide each side by "x" ;

" [x(y – 5)] / x  = 2/x " ; 

  →  y – 5 = 2/x  ;

Add "5" to each side of the equation:

y – 5 + 5 = 2/x + 5 ;

  →  y = 2/x + 5  ;  not a line;  since one cannot divide by "zero" ; there would be no "point" on the graph at "x = 0".  So, this answer choice:  [A] is correct.
_______________________________________________________
Choice [B]:
 
y -2x -18 = 0 

y - 2x = 18

y = 18 + 2x ;  y = 2x + 18 ; is a line.
_________________________________________________
Choice C)  3y + 12 - 6x = 5 ; 

3y = 5 - 12 + 6x ; 

3y = -7 + 6x ;  3y = 6x - 7 ;  y = 6x/3 - 7/3 ;  y = 2x - 7/3 ;  is a line.
_________________________________________________
Choice:  [D]:

2(y+x) = 0 ;

[2*(y+x)] / 2 = 0/2 ;  y + x = 0 ;  y = -x ;  is a line.

The population of a town can be modeled by P= 22,000 + 125t, where P represents the population and the t represents the number o
nlexa [21]
Given that the population can be modeled by P=22000+125t, to get the number of years after which the population will be 26000, we proceed as follows:
P=26000
substituting this in the model we get:
26000=22000+125t
solving for t we get:
t=4000/125
t=32
therefore t=32 years
This means it will take 32 years for the population to be 32 years. Thus the year in the year 2032

Find the length of EF
Lisa [10]

Answer:

9

Step-by-step explanation:

1. First, we need to set up an equation to find the value of x and then the length of EF.

2. We know that DG is equal to 33, so we can add all the three sections it's cut into altogether to get 33. Therefore, we get an equation of: 3x - 28 + 3x - 30 + x = 33

3. (Solving for x)

Step 1: Simplify both sides of the equation.

  • 3x - 28 + 3x - 30 + x = 33
  • (3x+3x+x) + (-28-30)=33
  • 7x - 58 = 33

Step 2: Add 58 to both sides.

  • 7x - 58 + 58 = 33 + 58
  • 7x = 91

Step 3: Divide both sides by 7.

  • \frac{7x}{7} = \frac{91}{7}
  • x = 13

4. Now that we know x is equal to 13, we can plug that value in for the expression 3x - 30.

  • 3(13)-30
  • 39 - 30
  • 9

Therefore, the length of EF is 9.
