Answer:
The perimeter of triangle is: [tex]\mathbf{10x^2-x+18}[/tex]
Step-by-step explanation:
We need to find perimeter, in terms of x, of the triangle shown here.
The length of side 1: [tex](7x^2 - 12)[/tex]
The length of side 2: [tex](-5x + 30)[/tex]
The length of side 3: [tex](3x^2 + 4x)[/tex]
The formula used to find perimeter of triangle is: [tex]Perimeter\: of\: triangle=Sum\:of\:length\:of\:all\:sides[/tex]
Putting values and finding perimeter:
[tex]Perimeter\: of\: triangle=Sum\:of\:length\:of\:all\:sides\\Perimeter\: of\: triangle=(7x^2 - 12)+(-5x + 30)+(3x^2 + 4x)\\Perimeter\: of\: triangle= 7x^2-12-5x+30+3x^2+4x\\Perimeter\: of\: triangle=7x^2+3x^2-5x+4x-12+30\\Perimeter\: of\: triangle=10x^2-x+18[/tex]
So, The perimeter of triangle is: [tex]\mathbf{10x^2-x+18}[/tex]
X+36 is less than 40 write equation
Answer:
x<4
Step-by-step explanation:
x+36 is less than 40
x+36<40
Subtract 36 from both sides
x<4This equation means, that in order for the equation to be true, x must be less than 4.
Answer:
x<4
Step-by-step explanation:
x+36=40
you do 36- 40 and get 4 then it would be x<4

Solve the system.... 2y+8x+58 and y-5x=11
Answer:
x=2, y=21
Step-by-step explanation:
there are two methods: substiution and elimation. I will be doing subtistution in this soultion:
first isolate y in either equation, it would be easier to do it in the second one.
y= 11+5x
Then, subtitute that into the first equation
2(11+5x)+8x=58 (it says 2y+8x+58 but I assume you mean 2y+8x=58?)
22+10x+8x=58
18x = 36
x=2
substitute that back into y = 11+5x, to get y=11+10 = 21
Can anyone help me with this question please .
Answer: y=-(5/4)x+5
Step-by-step explanation:
The parent function of a linear line is y=mx+b where m is the slope and b is the y intercept so:
Y=-(5/4)x+5

Answer:
90
Step-by-step explanation:
a triangle's angles all add up to 180. take 51 and 39 away from 180 and you get 90
Answer: 90 degrees
Step-by-step explanation:
Theorem:
a+b+c=180 degrees
39 degrees + 51 degrees + x degrees = 180 degrees
39 + 51 = 90
180 - 90 = 90
Max is flying a kite and gets tired of holding the string attached to the kite. Max has let out approximately 40 feet of string and the string makes a 32 degree angle with the ground. How high is the kite at the time?
Answer: i think 8
Step-by-step explanation:
What is the solution of each equation?
a
no solution
b
infinitely many solutions
c
8
d
-8
Answer:
b
Step-by-step explanation:
2(h-8)-h=h-16
step 1 distribute 2 to whats in the parenthesis
2h-16-h=h-16
step 2 combine like terms
h-16=h-16
add 16 to each side
h=h
subtract h from each side
0=0
this would have an infinite amount of solutions

For ΔABC, the measure in degrees of angles A, B, and C are 36, 3x, and 48 respectively. What is the value of x?
A
2
B
32
C
93
D
96
Answer:
B. 32
Step-by-step explanation:
[tex]\angle A + \angle B + \angle C = 180\\36 + 3x + 48 = 180 => 3x = 96 => x = 32[/tex]

bgbgbgbgbgbgbgbgbgbgbgbgbgbgbgbgbgbgbgbgbgbgbgbgbg
Step-by-step explanation:
What is the value of j?
___°
34 degrees.
If you want to find how much an angle is, first check the original line (aka base). Then (only if the line is a 180 degree line) subtract whatever value is shown (in this case it was 146 degrees so what you would do is subtract 146 from 180 and you would have your answer).
Hope this helps.

which of the following numbers is irrational
Answer:
E
Step-by-step explanation:
Irrational means cannot be put into a fraction. Or random repeating decimals is how I remember it.
√48 can be simplified to equal 4√3. √3 cannot be put into fraction form.
What is the image of the point (3,2)(3,2) after a rotation of 90^{\circ}90 ∘ counterclockwise about the origin?
Answer: = (-2,3)
Step-by-step explanation:
Rotation is a transformation of a figure by rotating it for a specific angle about a fixed point.Here, fixed point = origin = (0,0)
Transformation rule for rotation of [tex]90^{\circ}[/tex]counterclockwise about the origin:
[tex](x,y)\to (-y,x)[/tex]
Then, the image of the point (3,2) = (-2,3)
Hence, the image of the point (3,2) after a rotation of [tex]90^{\circ}[/tex]counterclockwise about the origin = (-2,3)
Answer: The answer is -2,3 because 90 degrees of the orgin :) enjoy
Step-by-step explanation:
How can you use the properties of equality to write equivalent equations?
If two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equal. When you solve an equation, you find the value of the variable that makes the equation true. In order to solve the equation, you isolate the variable.
a = b and c ≠0, then a c = a c . Another example Consider the equation 12 = 12. Divide both sides by 4.
14 is 33 1/2% of what number?
Answer:
41.79
Step-by-step explanation:
c = 14 * 100/33.5 = 1400/33.5 = 2800/67
= 41.79104
