The length of a rectangular poster is 7 inches more than twice its width. Find the length of the poster if its perimeter is 110
lakkis [162]
Let W = width of poster 
Since the length is 7 inches longer than the width, the length is represented by W + 7. 
We know the perimeter is equal to twice the length + twice the width and that is 110 inches. Mathematically that looks like: 
2(W + 7) + 2(W) = 110
Now let's solve for W: 

2(w+7)+2w=110

Step 1: Simplify both sides of the equation.

2(w+7)+2w=110

Simplify: (see simplify steps down below)

4w+14=110

Step 2: Subtract 14 from both sides.

4w+14−14=110−14

4w=96

Step 3: Divide both sides by 4.

4w4=964

w=24

Answer:

w=24

Simplify Steps:
(2)(w)+(2)(7)+2w=110(Distribute)

2w+14+2w=110

(2w+2w)+(14)=110(Combine Like Terms)

4w+14=110

To see if the slopes are the same, write an equation setting the two fractions equal to each other. Is this equation true? Why o
RoseWind [281]

Answer:

Slope(EA)=Slope(AC)=\dfrac{2}{3}....Equation is True

Slopes are EQUAL for

  1. SAME Line

Hence, E-A-C is the same Line.

Step-by-step explanation:

Given:

The three points for the given line are

point E( x₁ , y₁) ≡ ( -6 ,-4)

point A( x₂ , y₂) ≡ (0 , 0) .....Origin

point C(x₃ , y₃ ) ≡ (3 ,  2)

To Find:

Slope EA = ?

Slope AC = ?

Solution:

For Two point Slope is given as

Slope=\dfrac{y_{2}-y_{1} }{x_{2}-x_{1} }

Substituting the values we get

Slope(EA)=\dfrac{0--4}{0--6}=\dfrac{4}{6}=\dfrac{2}{3}

Similarly For AC we have,

Slope(AC)=\dfrac{2-0}{3-0}=\dfrac{2}{3}

Therefore,

Slope(EA)=Slope(AC)....Equation is True

Slopes are EQUAL for

  1. Line is Parallel
  2. SAME Line

Hence, E-A-C is the same Line.
