Answer:
Part a) 
Part b) The expression that represent the cost of fencing the field is 
Part c) 
Step-by-step explanation:
<u>The complete question in the attached figure</u>
Part a) we know that
The perimeter of the rectangular field (excluding the width of the gate) is equal to

we have

substitute the given values


Part b) we know that
To find out the cost of fencing the field (excluding the gate) , multiply the perimeter by the cost of $28 per yard
so

Part c) we have
h=5
substitute the value of h in the expression of the cost

Answer:
v = -16
Step-by-step explanation:
<u>→Distribute the 5 to (-7v - 11):</u>
14 - 10v + 11 = 20v - 35v - 55
<u>→Add like terms:</u>
25 - 10v = -15v - 55
<u>→Add 15v to both sides:</u>
25 + 5v = -55
<u>→Subtract 25 from both sides:</u>
5v = -80
<u>→Divide both sides by 5:</u>
v = -16
Answer:
Ok, so when you graph, you want to make sure your point are right. 4, would be im guessing +4, so you would find +4, on your graph across the X axis. Keep that in mind. Then find +3, across the Y axis on your graph. Join the points, and you have your answer.
Step-by-step explanation:
