Answer:

B length = 8 in.; width = 4 in

Step-by-step explanation:

Given

the length L = w + 4

Perimeter = 24 inches

Perimeter of a rectangle

= 2(L + W)

We now have two equations.

Equation 1: L = w + 4

Equation 2: P = 2(L + W)

Substitute L as w + 4 into equation 1. And 24 for p

Therefore

24 = 2(w + 4 + w)

24 = 2(2w + 4)

Distribute 2 into (2w + 4)

We have

24 = 2 x 2w + 2 x 4

24 = 4w + 8

Subtract 8 from both sides

24 - 8 = 4w + 8 - 8

16 = 4w

Divide both sides by 4

16/4 = 4w/4

4 = w

w = 4 inches

Now substitute 4 for w into either of the equations to get

L.

Using equation 1 , we have

L = w + 4

L = 4 + 4

L = 8 inches

Ms. Wilson draws a model of the factorization of a polynomial with integer factors. Her model is partially complete.

I'll just factor the above equation.

x² + 18x + 80

x² ⇒ x * x
80
can be:
1 x 80
2 x 40
4 x 20
5 x 16
8 x 10  Correct pair

(x+8)(x+10)
x(x+10) +8(x+10) ⇒ x² + 10x + 8x + 80 = x² + 18x + 80

x+8 = 0
x = -8

x+10 = 0
x = -10

x = -8

(-8)² + 18(-8) + 80 = 0
64 - 144 + 80 = 0
144 - 144 = 0
0 = 0

(-10)² + 18(-10) + 80 = 0
100 - 180 + 80 = 0
180 - 180 = 0
0 = 0

I think the algebra tiles will not be a good tool to use to factor the quadratic equation because the equation is not a perfect square quadratic equation.

The two graphs below compare the gallons of gasoline used and the total distance traveled for two different cars.
Taya2010 [7]

Answer:

s₁ > s₂

Is accurate comparison

Step-by-step explanation:

If we have two different point for a straight line the slope of such line is given by:

P₁ = ( x₁ , y₁ )        P₂ = ( x₂ , y₂ )

The slope of the line is

s₁ = (y₂ - y₁ ) / ( x₂ - x₁)

Then for the pairs of points:

P₁ (2 , 50 )     and P₂ ( 4 , 100)

y₂  -  y₁   =  100 - 50    ⇒     y₂  -  y₁   = 50

and

( x₂ - x₁ )   ⇒  4 - 2  =  2

Then

s₁ =  50/2  

s₁  = 25

In the second case

Points

P₁ ( 2 , 40 )     P₂ ( 4 , 80 )

s₂ = (y₂ - y₁ ) / ( x₂ - x₁)

y₂  -  y₁   =  80 - 40  = 40

x₂ -  x₁  = 4 - 2  = 2

s₂  =  40/2

s₂ = 20

Then

s₁ > s₂

Is accurate comparison
