Hi,
Let's solve the equation step-by-step.
x−3x=2(4+x)
Step 1: Simplify both sides of the equation.
x−3x=2(4+x)
x+−3x=(2)(4)+(2)(x)(Distribute)
x+−3x=8+2x
(x+−3x)=2x+8(Combine Like Terms)
−2x=2x+8
−2x=2x+8
Step 2: Subtract 2x from both sides.
−2x−2x=2x+8−2x
−4x=8
Step 3: Divide both sides by -4.
−4x/−4 = 8/−4
x=−2
Answer:
x=−2
Have a great day!
Answer:
Step-by-step explanation:
f(-9+h)= (-9+h)² = h²-18h+81
f(-9+h)-f(-9)=h²-18h+81 -81 because : f(-9) = (-9)² = 81
f(-9+h)-f(-9)=h²-18h
(f(-9+h)-f(-9))/h=(h²-18h)/h = h(h-18)/h =h-18
lim (f(-9+h)-f(-9))/h = lim(h-18= - 18
h→0 h→0
Answer:

Step-by-step explanation:
x - length of side of larger hexagon
y - length of side of smaller hexagon
We know that,
x/y = 
y = 
Hence,
perimeter of =
* perimeter of smaller hexagon
larger hexagon

Answer:
The required equation is 5x - 3 = 12
Step-by-step explanation:
We have to find the equation for the given condition
Let the number be x as given in the equation
Now according to the condition
5 time the Number is 5 *x = 5x
Three less then 5 time the Number would be 5x - 3
And all of it is equal to 12
Which gives us the equation
5x - 3 =12
The required equation is <em>5x - 3 = 12</em>
