Area is Length x width:
(2x+5) * x = 420
Distributive property:
2x^2 +5x = 420
Subtract 420 from both sides:
2x^2 + 5x - 420 = 0
Using the quadratic formula:
a = 2, b = 5, c = -420:
-5 +/ √5^2 -4*(2*-420) / 2*2
x = 13.2951
Rounded to the nearest hundredth = 13.30 inches.
Answer:
Following are the responses to the given choices:
Step-by-step explanation:
In step 1:
State the zero and alternate test hypotheses. Insert underneath.
Smaller companies in their region are and they spend at least 24 hours per week on the marketing of the these companies
There really is no growth for smaller firms in their area because the companies spend or less 24 hours per week on marketing.
In step 2:
Each test statistics meaning is calculated. Around two decimal places for your reply.
In step 3:
Draw a start and write the decision.
Since it is observed that 
it is then concluded that the null hypothesis is rejected.
Consequently we consider that small companies in their field may not expand, as they spend or less 24 hours per week on marketing.
The answer:
the full question is as follow:
<span>Point F is on circle C. What is the length of line segment GF?
12.5 units
15.0 units
17.5 units
20.0 units
according to the image, GF= GC + CF
CF is the radius of the circle, so it is CF =CE = 7.5
all that we want to find is the value of GC
let's consider the triangle GEC. This is a right triangle, so for finding GC, we can apply Pythagorean theorem
that is, GE² + EC² = GC², and from this, we have GC = sqrt(</span>GE² + EC² )
GC = sqrt(10² + 7.5² )=sqrt(56.25)=12.5
<span>
therefore, </span>GF= GC + CF=12.5 + 7.5 = 20.0
the answer is 20.0 units
