Answer: find the answer in the explanation.

Step-by-step explanation:

You are given that the sides of a rectangle are a number and 4 less than that same numbers.

Let the length side = L

And width side = L - 4

The dimensions of the rectangle will be

Area = length × width

L × ( L - 4 )

Open the bracket

L^2 - 4L

The verbal expression here,

Perimeter = L + L + W + W

Substitute all the parameters into the formula

56 = L + L + L-4 + L-4

56 = 2L + 2L - 8

56 = 4L - 8

Graph the given relation or equation and find the domain and range. Then determine whether the relation or equation is a functio
crimeas [40]

Answer:

The graph is attached.

Domain:\ All\ Real\ Numbers\\\\Range:\ All\ Real\ Numbers

The relation is function.

Step-by-step explanation:

Find the x-intercept. Substitute y=0 into the equation and solve for "x". Then, this is:

 0=2x+2\\\\x=\frac{-2}{2}\\\\x=-1

The equation of the line in Slope-Intercept form is:

y=mx+b

Where "m" is the slope and "b" is the y-intercept.

In this case "b" is:

b=2

Therefore, since the line passes through the points ((-1,0) and (0,2), you can graph it. (Observe the graph attached)

Since it is a line, then <em>the relation is a function</em>, and the Domain and the Range of Linear Functions are:

Domain:\ All\ Real\ Numbers\\\\Range:\ All\ Real\ Numbers

Answer:

Arc DE = 70°

Arc RST = 206°

Step-by-step explanation:

arc DE + arc DC = 180° because EC is a diameter

7x + 7 + 11x + 11 = 180°

combine like terms:

18x + 18 = 180°

subtract 18 from both sides of the equation:

18x = 162°

divide both sides by 18:

x = 9

Arc DE = 7(9) + 7 = 70°

arc RST = 2(x + 103) = 2x + 206

arc RFT = 2(x + 77) = 2x + 154

arc RST + arc RFT = 360°

so:

2x + 206 + 2x + 154 = 360°

combine like terms:

4x + 360 = 360

4x = 0

x = 0

arc RST = 2x + 206 = 206°
