The polygons below are smlar, find the vdue of x. N 30 24 32 25 X+4. pe your answer...
Answer:
11
Step-by-step explanation:
If they are similar the ratios of lengths are the same.
30:24 = (x+4):12
2(x+4):24
2(x+4)=30
x+4=15
x=11
x + 16 = 25 What is the value of x?
Answer:
x = 9
Step-by-step explanation:
Isolate x first by moving 16 to the other side
x = 25 - 16
x = 9
May someone please help? I have a D in math and need to bring it up!!
Answer:
x=+7, x=-7
Step-by-step explanation:
3x^2=131+16
3x^2=147
x^2=147/3
x^2=49
x=[tex]\sqrt{49}[/tex]
x=+7
x=-7
Answer:
A. -7
Step-by-step explanation:
You want x by itself, so first, add 16 on both sides to get 3x^2=147. Next, divide by 3 on both sides to get x^2=49. You're left with -7 and 7 as possible answers since both squared can equal 49. The smallest answer would be -7 in this situation.
(7).Given f(x) =
[tex] \frac{1}{x ^{2} - 1} [/tex]
and g(x)=
[tex] \frac{x}{x + 2} [/tex]
where x & R.
Find the ;
(i). inverse of g(x) (ii). Expression
[tex] g{x} ^{ - 1} f{x}[/tex]
iii). Largest domain of f(x) and g(x) respectively.
Answer:
The inverse of g(x) is [tex]g^{-1}(x)=\frac{2x}{1-x}[/tex]
The domain of g(x) is (-∞,-2)U(-2,∞)
The domain of f(x) is (-∞,-1)U(-1,1)U(1,∞)
Step-by-step explanation:
Find the inverse of g(x).
[tex]y=\frac{x}{x+2}[/tex]
Solve for x
[tex]x=y(x+2)[/tex]
[tex]x=xy+2y[/tex]
[tex]x(1-y)=2y[/tex]
[tex]x=\frac{2y}{1-y}[/tex]
[tex]g^{-1}(x)=\frac{2x}{1-x}[/tex]
Find the domain of g(x)
[tex]g(x)=\frac{x}{x+2}[/tex]
Numerator and denominator have domain
(-∞,∞).
However, g(x) is undefined if the denominator is 0. Hence, x=-2 must be taken out of the domain. So, the domain of g(x) is
(-∞,-2)U(-2,∞).
Find the domain of f(x)
[tex]f(x)=\frac{1}{x^{2} -1}[/tex]
The numerator and denominator have the domain
(-∞,∞)
However, f(x) is undefined if the denominator is 0. This rules out +1 and -1. So, the domain of f(x) is
(-∞,-1)U(-1,1)U(1,∞)
I am not sure what you mean for (ii).

Law of Cosines: C2 = 22 + b2 - 2ab cos C
Answer:
22.1°
Step-by-step explanation:
cos^-1(x) = (8² - 19² - 14²) ÷ -2(14)(19)
cos^-1(x) = -493 ÷ -532

A square piece of land is to be divided into 4 square quadrants of equal size. On a map, the entire piece of land measures 6 inches long on each side.
The scale of the map is inch = 20 feet. How much area will be included in each quadrant when the piece of land is divided?
A.43,200 ft2
B.27,000 ft2
C.14.400 ft2
D.10,800 ft2
Answer:
The scale of the map is inch = 20 feet.
This statement must be incorrect or the fraction of the inch is missing.
Because 6" long, at a scale of one inch = 20 feet, would only be 120 feet x 120 feet.
120 x 120 = 14,000 ft^2 and each of the four quadrants wouls only be 3600 ft^2.

The cost of 5m of cloth is ₹450. The cost of 8m of cloth is
Step-by-step explanation:
Rs 720
Cost of 1 m of cloth = 450/5= Rs 90
Cost of 8 m of cloth= 90*80= Rs 720
Answer:
The cost is Rs. 720
Step-by-step explanation:
The cost of 1 meter cloth is Rs.90
So 8 x 90 = 720
-20y + 10y + 10 + 10 = -40
Answer:
y = 6
Step-by-step explanation:
-20y + 10y + 10 + 10 = -40
-20y + 10y = -40 - 10 - 10
-20y + 10y = -60
-10y = -60
y = -60/-10
y = 6
correction* heres my question, 6th grade math.
Answer:
(A) If you write the coordinates on a graph, you can find the distance between the drinking fountain and bench by applying the distance formula: (x2-x1)^2 + (y2-y1)^2. So this is how to solve it:
1. (0--4)^2+(2-2)^2
2. (0+0)^2+(2-2)^2
3. (4)^2+0
4. √16
5. 4
___________________________________
(B) This is a right triangle because if you plot the points on a graph, it creates the shape of a right triangle.

Step-by-step explanation:
Write an equation that passes through the points (5, 9) and (2, 6).
Answer:
y= 1x+4
Step-by-step explanation:
y= mx+b
(y2 - y1) / (x2 - x1)= 6-9/2-5
m= -3/-3
m= 1
we can use either (5, 9) or (2, 6). we'll use (2,6)
6= 1*2+b
6= 2+b
6-2= 2+b-2
4= b
so, y= 1x+4
