The perimeter is 21cm. What is the value of x?
Answers
you know 2x+5+3x+1+x=21
you can simplify this to 6x + 6 = 21cm
you can then take away 6 from both sides
leaving you with 6x = 15
divide those by 6
leaving you with x = 2.5
you can then check this by doing 2.5 times 6 = 15
then 15 + 6
= 21

Answers
Answer:
[tex]\boxed{\sf{x=8}}[/tex]
Step-by-step explanation:
It is necessary to isolate one side of this equation in order to find the solution.
4x+3=35
First, subtract by 3 from both sides.
[tex]\sf{4x+3-3=35-3}[/tex]
Solve.
Subtract.
35-3=32
[tex]\sf{4x=32}[/tex]
Then, divide by 4 from both sides.
[tex]\sf{\dfrac{4x}{4}=\dfrac{32}{4}}[/tex]
Solve.
Divide.
32/4=8
[tex]\Rightarrow \boxed{\sf{x=8}}[/tex]
Therefore, the solution is x=8, which is our answer.
I hope this helps, let me know if you have any questions.
Answer: x = 8
Step-by-step explanation:
4x + 3 = 35
4x = 35-3
4x = 32

Answers
Answer:
They can never be similar because their sides can never be proportional and their angles can never be congruent.
Step-by-step explanation:
Hope It Helps
I did the k12 test!!
They can never be similar because their angles can never be equal and their sides can never be proportional.
What are Similar Triangles?Two triangles are said to be similar if the triangles are of the same shape but different size. The angles of the triangle will be equal and the sides are proportional.
An equilateral triangle has all the sides and angles equal to each other.
Any similar triangle for an equilateral triangle will have the sides proportional.
Since all the sides are equal, the similar triangle will also have all the sides equal which may be different from the original triangle.
So this can never be similar to a scalene triangle where all the sides are of different length.
Hence the correct reason is that, their angles can never be equal and their sides can never be proportional.

The population of Missoula, MT was 67,358 people in 2010. What was the increase if there were 75,516 people in 2019? What was the average increase per year?
Answers
Answer: 906
Step-by-step explanation:
75,516-67,358= 8,158
2019-2010= 9 years
8,158÷9= 906
The increase in the population is 8158 and average increase in the population per year is 906.4.
What is Subtraction?Subtraction can be done for any numbers or algebraic expressions. It is the process of taking out certain value from a given amount of number.
The process of subtraction can also be termed as finding difference.
Given that,
Population of Missoula in 2010 = 67,358
Population of Missoula in 2019 = 75,516
Increase in the population = 75,516 - 67,358 = 8158
Average increase in the population per year = 8158 / (2019 - 2010)
= 8158 / 9
= 906.4
Hence the increase in the population is 8158 and average increase per year is 906.4.

Answer:
y = 4x + 4
Step-by-step explanation:
The equations in the options are all in the slope-intercept form, y = mx + c. In this form, m is the slope while c is the y-intercept.
The slope of a line can be found using the formula below:
[tex]\boxed{\text{Slope}=\frac{y_1-y_2}{x_1-x_2} }[/tex]
In the formula, [tex](x_1, y_1)[/tex] is the first point and [tex](x_2, y_2)[/tex] is the second point on the graph.
Let's identify the two points in the graph which we can use to calculate the slope.
The 2 given points are: (-2 , -4) and (0 , 4)
Substituting the 2 pairs of coordinates into the slope formula:
Slope
[tex]=\displaystyle{\frac{-4-4}{-2-0}}[/tex]
[tex]\displaystyle{=\frac{-8}{-2}}[/tex]
= 4
Substitute the value of the slope into m:
y = 4x + c
The y-intercept, c, is the y value in which the line cuts through the y-axis (vertical axis). It is also the y-coordinate of the point when the x = 0.
In this question, we are given the point (0 , 4) which is also the y-intercept.
Substitute c = 4 into the equation:
y = 4x + 4
Thus, the equation shown in the graph is y = 4x + 4.
