Answer:
1. Perimeter = 8x m
2. Area = 3x² m²
Step-by-step explanation:
From the question given above, the following data were obtained:
Breadth (B) = x m
Length (L) = 3B = 3x m
Perimeter (P) =?
Area(A) =?
1. Determination of the perimeter of the rectangle.
Breadth (B) = x m
Length (L) = 3x m
Perimeter (P) =?
P = 2(L + B)
P = 2(3x + x)
P = 2(4x)
P = 8x m
Thus, the perimeter of the rectangle is 8x m
2. Determination of the area of the rectangle.
Breadth (B) = x m
Length (L) = 3x m
Area(A) =?
A = L × B
A = 3x × x
A = 3x² m²
Thus, the area of the rectangle is 3x² m²

find the exact value of x.
Answer:
x = 4 sqrt(3)
Step-by-step explanation:
x is not to be confused by the mark on the right angle -- X
The function is the cosine of Y which is 30 degrees.
The cosine of 30o is sqrt(3)/2
cos(30) = adjacent side / hypotenuse = sqrt(3) / 2
The adjacent side is 6
cos(30) = 6/ x = sqrt(3) / 2
6/x = sqrt(3) / 2 Cross multiply
x * sqrt(3) = 6 * 2
x * sqrt(3) = 12 divide by sqrt(3)
x = 12 / sqrt(3) Multiply top and bottom by sqrt(3)
x = 12* sqrt(3) / sqrt(3) * sqrt(3)
x = 12 sqrt(3)/ 3 Divide by 3
x = 4 sqrt(3)

Gary draws this sequence of patterns of white and grey squares. The sequence is continued. How many grey squares will there be with 16 white squares?
Answer:
20 gray squares
Step-by-step explanation:
Given
See attachment for squares
Required
Number of gray squares when white = 16
First, we calculate the equation that represents both squares.
The white squares
[tex]a = 2[/tex] --- initial
[tex]d = 4 - 2 = 6 - 4[/tex]
[tex]d = 2[/tex] -- difference between successive gray squares
So, the nth term is:
[tex]W_n = a + (n - 1)d[/tex]
[tex]W_n = 2 + (n - 1)*2[/tex]
[tex]W_n = 2 + 2n - 2[/tex]
[tex]W_n = 2n[/tex]
The gray squares
[tex]a = 6[/tex] --- initial
[tex]d = 8-6=10-8[/tex]
[tex]d = 2[/tex] -- difference between successive gray squares
So, the nth term is:
[tex]G_n = a + (n - 1)d[/tex]
[tex]G_n = 6 + (n - 1) *2[/tex]
[tex]G_n = 6 + 2n - 2[/tex]
[tex]G_n = 4 + 2n[/tex]
When the white squares is 16
[tex]W_n = 16[/tex] --- Calculate n
[tex]W_n = 2n[/tex]
[tex]16 = 2n[/tex]
[tex]8 = n[/tex]
[tex]n = 8[/tex]
To get the number of gray squares;
Substitute [tex]n = 8[/tex] in [tex]G_n = 4 + 2n[/tex]
[tex]G_n = 4 + 2 * 8[/tex]
[tex]G_n = 20[/tex]

The average color of the population would become paler would living in White Sands National Monument for a few generations change a population of eastern fence lizards. Hence, option C is correct.
What Is White Sands National Monument worth visiting?It's difficult to travel to White Sands National Park, and there aren't many things around to keep you very busy. It's a peaceful area with peculiar traits and uncommon lifeforms. Not everyone can benefit from it, but some of us can. If you go, sand will likely go in your eyes as well as your boots.
Plan to spend a whole day in White Sands National Park for the finest experience. Early in the morning, before the tourists gather and the warmth rises, hike the Alkali Flat Trail. Have a picnic lunch and go sledding on the dunes around noon. One of the shorter hiking trails is another option.
Thus, option C is correct.

The measure of the smallest angle of a triangle is 34 less than the measure of the largest angle of the triangle. The measure of the third angle is more than the measure of the smallest angle. Find all three measures .
Answer:
45degrees, 79egrees and 56degrees
Step-by-step explanation:
Complete question:
The measure of the smallest angle of a triangle is 34 less than the measure of the largest angle of the triangle. The measure of the third angle is 11 more than the measure of the smallest angle. Find all three measures .
Let the smallest angle be x
Let the largest angle be y
Let the third angle be z
Since the sum of angle in the triangle is 180, then x+y+z = 180 .. 1
If the measure of the smallest angle of a triangle is 34 less than the measure of the largest angle of the triangle, this is expressed as;
x = y - 34
y = x + 34 ..... 2
If the measure of the third angle is 11 more than the measure of the smallest angle, this is expressed as;
z = x + 11 .... 3
Substitute 2 and 3 into 1;
x + (x+34) + (x+11) = 180
x+x+x+45 = 180
3x+45 = 180
3x = 180 - 45
3x = 135
x = 135/3
x = 45 degrees
From 2;
y = x+34
y = 45 + 34
y =79degrees
From3;
z = x+11
z = 45 + 11
z = 56degrees
Hence the measure of the angles are 45degrees, 79egrees and 56degrees

What is the distance between points S and U if S is 2, 1 and U is 6, 8
Round to the nearest tenth of a unit.
A. 3.3 units
B. 6.4 units
C. 8.1 units
D. 12.0 units
The distance formula is:
D = sqrt((x2-x1)^2 + (y2-y1)^2)
D= sqrt ((6-2)^2 + (8-1)^2)
D = sqrt(4^2 + 7^2)
D = sqrt( 16 + 49)
D = sqrt(65)
D = 8.06
Rounded to the beat tenth = 8.1 units.
The answer is C. 8.1 units
Answer:
C
Step-by-step explanation:
S has coordinates (2 , 1) and U has coordinates (6, 8) . Computing the SU vector gives us (4 , 7)
taking the distance formula : sqrt(4^2 +7^2)
= sqrt(65) = 8.1 which is answer C

So looking at the larger main triangle...
the top angle is composed of two angles measuring 40° and 41°. So it is equal to 81°.
The angle on the lower left side is a supplimentary angle with the one that measures 110°. The two of them combined make a line. A straight line is 180°, so that angle is 70°. (180 - 110)
The final angle in the triangle is accross from x. This makes them a pair of vertical angles, so therefore congruent.
The angles of a triangle add up to 180°
We already know the other two angles so 180 - 81 - 70 = 11°
so x is also 11°
