The length of Bryan’s garden is 4 meters longer than 3 times the width. The perimeter of his garden is 72 meters. What are the dimensions (l, w) of his garden?
Answer:
8 m = width
28 m = length
Step-by-step explanation:
Let w = width
3w + 4 = length
P = 2w + 2l
= 2w + 2(3w + 4) = 72
2w + 6w + 8 = 72
8w + 8 = 72
8w = 64
w = 8 m = width
3w + 4 = 24 + 4 = 28 m = length

9m + 19 − 14 + 4n Please solve.
Answer:
9m+4n+5
Step-by-step explanation:
9m
19 - 14 = 5
4n
so we can combined the 9m,5,4n to 9m+4n+5
Answer:
9m+4n+5
Step-by-step explanation:
Combine the like terms:
9m+19+-14+4n
=(9m)+(4n)+(19-14)
=9m+4n+5
I want to take the measurements of my 5 avocado trees and order their
heights from shortest to tallest, that way they can get enough sunlight to
continue growing. I have to worry about sea level, so those above sea
level get sunlight more easily (positive is above sea level, negative is
below sea level). The 5 heights are in feet: 6,-3, 2,-8,-6. Please help me
order them from shortest to tallest so I plant them in the right order to get
enough sunlight.
Answer:
If we are saying everyhing above sea level is taller then plants under sea level. Then here is the order
Step-by-step explanation:
-8, -6, -3, 2, 6
And just in case it's above sea level the shortest then 6, 2, -3, -6, -8

Explanation:
First we'll focus on triangle DEH. Ignore the other points and values.
We have the sides of EH = 32 and DH = 49. Let x be the measure of angle DHE, which is one of the pieces of angle DHG. We'll use the cosine rule to find x.
cos(angle) = adjacent/hypotenuse
cos(H) = EH/DH
cos(x) = 32/49
x = arccos(32/49)
x = 49.227195
The value is approximate and rounded to 6 decimal places. Make sure your calculator is in degree mode. Arccos is the same as inverse cosine.
We'll come back to this value later.
---------------------
Now focus on triangle HFG. Ignore the other points.
We have the sides of FG = 38 and GH = 43
Let y be the measure of angle FHG, which is the missing piece to form angle DHG. Based on how x and y are set up, we can say x+y = angle DHG.
To find y, we'll need the sine rule this time
sin(angle) = opposite/hypotenuse
sin(H) = FG/GH
sin(y) = 38/43
y = arcsin(38/43)
y = 62.094527 which is approximate to 6 decimal places
---------------------
The last step is to add the values of x and y we found earlier
angle DHG = (angle DHE) + (angle FHG)
angle DHG = (x) + (y)
angle DHG = (49.227195) + (62.094527)
angle DHG = 111.321722
angle DHG = 111 degrees after rounding to the nearest whole degree.
----------------------
If you wanted to do this all in one step, you could say:
arccos(32/49)+arcsin(38/43) = 111.3217 which rounds to 111 degrees.

C
Step-by-step explanation:
A population of rabbits doubles every 4 months. If the population starts out with 8 rabbits how many will there be in 1 year
Given:
The initial population of rabbit = 8
Population of rabbits doubles every 4 months.
To find:
The number of population in 1 year.
Solution:
The exponential growth model is
[tex]y=a(b)^x[/tex] ...(i)
Where, a is the initial population, b is growth factor, x is time period.
We know that,
12 month = 1 year
So, there are 3 time period of 4 months in an year.
Initial population of rabbit (a) = 8
Population of rabbits doubles every 4 months. So, growth factor is 2, i.e., b=2 and the time period is 3, i.e., x=3.
Putting a=8, b=2, x=3 in (i), we get
[tex]y=8(2)^3[/tex]
[tex]y=8(8)[/tex]
[tex]y=64[/tex]
Therefore, the population of rabbit in 1 year will be 64.

The base and the height of Triangle A are half the base and the height of Triangle B. How many times greater is the area of Triangle B?
The area of Triangle B is
times greater
Answer:
Let's say that the base of triangle a is 2 and the height is 3. That makes the base and height of triangle b 4 and 6. To find the area of a triangle, use the formula 1/2 multiplied by height multiplied by base. So the area of triangle a is 2 multiplied by 3 multiplied by 1/2 giving us 3. The area of triangle b is 1/2 multiplied by 4 multiplied by 6 giving us 12. Since 12 divided by 3 is 4, the area of triangle b is 4 times greater than the area of triangle a.

Write the equation for an exponential function that triples ever year, x, when the original amount is 4.
Answer:
y = 4(3)^x
Step-by-step explanation:
Here, we want to write the exponential equation
From the question, we have the equation tripling in x value every year and the original amount is 4
The exponential equation is of the form;
y = a(b)^n
In this case;
a = 4 , b = 3 and n = x
So we have the equation as;
y = 4(3)^x

(Help please) Find both the perimeter and the area of the following rectangle
2x+3
X+6
Perimeter:_____
Area:____
Given:
Length of a rectangle = (2x+3) units
Width of the rectangle = (x+6) units
To find:
The perimeter and the area of the rectangle.
Solution:
We know that, the perimeter of the rectangle is
[tex]Perimeter=2(Length+Width)[/tex]
[tex]Perimeter=2((2x+3)+(x+6))[/tex]
[tex]Perimeter=2(3x+9)[/tex]
[tex]Perimeter=6x+18[/tex]
The area of rectangle is
[tex]Area=Length\times width[/tex]
[tex]Area=(2x+3)\times (x+6)[/tex]
[tex]Area=2x^2+12x+3x+18[/tex]
[tex]Area=2x^2+15x+18[/tex]
Therefore, [tex]Perimeter=6x+18[/tex] and [tex]Area=2x^2+15x+18[/tex].
