Step-by-step explanation:

Answer:

− 4x + 12

ENJOY...

Step-by-step explanation:

Answer:

12 - 4x

Step-by-step explanation:

Distribute the 4 to both terms within the parentheses:

4(3 - x)

4*3 - 4*x

12 - 4x

This is called the expanded form, while 4(3 - x) is called the factored form of this expression.

Hope this helps!! :)

Answer: I don't know how to do the first question but I think I did the 2nd question correctly I believe we learned this in 7th grade.  I am a freshman so if it is wrong I am sorry anyways the answers for #2 are

A: 34 for JK

B: 15 for MN

and C: 30 for JL

Perimeter: is 79.  

This was fun to do lol ik it wasn't much but better than nothing.

Answer:

Step-by-step explanation:

First Question: Equilateral triangles all have the same interior angles. 60 degrees. Size does not make the angles bigger. It makes the sides bigger.

Second Question: No the size does not influence the size of the interior angle.

Third Question: That's true for all polygons. Size is not affect the interior angle size.

Answer:

7

Step-by-step explanation:

Plug it in.....

h(0) = 2.5 * 0 + 7 = 7

11.7

Formula: a^2 + b^2 = c^2

so substitute the numbers like this:

10^2 + 6^2 = c^2

both 10^2 and 6^2 are perfect squares:

10 × 10= 100 and 6 × 6= 36

100 + 36= c^2

add:

100 + 36 =

136 = c^2

now in order to get rid of the squared, you put it into a radical:

√136 = √c^2

note: whatever you do on one side, you do to the other

it's easier to use the calculator for this so put √136 and you're gonna get 11.66

since it's asking you to round it to the nearest tenth:

11.66 = 11.7

sorry if the explanation is kinda long ✋ i tried explaining it better in the end but i failed

Answer:

Step-by-step explanation:

Your answer

About all the sides are equal so we can say (10x + 44) side's triagle is twice than another triangle

So, 10x + 44 = 2( 8x - 23)

..... 10x +44 = 16x -46

...... X = 15

Answer:

x = 7.4

Step-by-step explanation:

cos(42°) = x/10 or distance from bases / rope length

Using the calculator find the value of cos(42°):

cos(42°) = 0.74 = x/10

Find x using the value of cos(42°):

x/10 = 0.74

x = 7.4

Answer:

Step-by-step explanation:

perimeter=2(125+80)=2(205)=410 yards

let the length of new rectangle be x and y.

Perimeter=2(x+y)

2(x+y)=410

x+y=410/2=205 yards

y=205-x

area A=xy=x(205-x)=205x-x²

[tex]\frac{dA}{dx} =205-2x\\\frac{dA}{dx}=0,gives~205-2x=0\\x=\frac{205}{2}\\\frac{d^2A}{dx^2}=-2<0 ~at~x=\frac{205}{2}\\[/tex]

A is maximum at x=205/2

y=205-205/2=(410-205)/2=205/2

so x=205/2=102.5 yards

y=205/2=102.5 yards

Answer:

9

Step-by-step explanation:

Simplfiy

x=3

Hi! Your answer is x = 3.

Please see an explanation for a clear and better understanding to your problem.

Any questions about my answer and explanation can be asked through comments! :)

Step-by-step explanation:

Our goal is to find the value of x. That means what we have to do is to isolate x-term first.

[tex]\huge{x+10=13}[/tex]

To isolate a variable means that to make a variable as a subject or also known as leaving a variable alone. To isolate the x-term for this problem, simply subtract both sides by 10 so we can get rid of 10 from the left side.

[tex]\huge{x+10-10=13-10}\\\huge{x+0=3}\\\huge{x=3}[/tex]

If you are not sure that the answer is correct or not. We can substitute the value of x in the equation.

[tex]\huge{x+10=13}[/tex]

Substitute x = 3 in the equation.

[tex]\huge{3+10=13}\\\huge{13=13}[/tex]

The equation is true for x = 3. Hence, we can conclude that x = 3 is the solution to the equation.

Answer:

[tex]2(x+2)/x+1[/tex]

Step-by-step explanation:

Answer:

2( x +2 )

x+1

Step-by-step explanation:

to add or subtract expressions expand them to make their denominators the same, multiply 1 time [tex]\frac{x-2}{x-2}[/tex]

since [tex]\frac{x}{x-2}[/tex] and [tex]\frac{x-2}{x-2}[/tex] have the same denominators add them by adding their numerators

combine x + x -2

factor [tex]x^{2}[/tex] - 4

to add or subtract expressions expand them and multiply by 1

have same denominator add them by adding their numerators

do the multiplications in 3 + ( x-2 )(x+2)

combine like terms in 3 + [tex]x^{2}[/tex] + 2x - 2x -4

divide [tex]\frac{2x-2}{x-2}[/tex] by [tex]\frac{-1 + x^{2} }{(x-2)(x+2) }[/tex] multiplying [tex]\frac{2x-2}{x-2}[/tex]

cancel out x-2 in both numerator and denominator

factor the expression that are not already factored

cancel out x-1  in both numerator and denominator

expand the expression

Answer:

Step-by-step explanation:

A certain number of nickels, dimes and quarters have a value of $5.60 there are an equal number of each type of coin. How much coins are there?

(0.05+0.10+0.25)c =5.60

0.40c=5.60

40c=560

c = 14

There are 14 nickels ,dimes and quarters.

Step-by-step explanation:

G(x) = 2/3 x - 6     switch x and y around and solve for y.

y = 2/3 x - 6

x = 2/3 y - 6

x + 6 = 2/3 y

3/2  x + 9 = y

Answer:
