Answer:
The area would be '15l - l²
Step-by-step explanation:
Given,
By 30 feet of wire fencing we need to make a rectangular shape,
Thus, perimeter of such rectangle = 30 feet,
We know that,
Perimeter of a rectangle = 2( length + width)
if length = l feet,
⇒ 2(l + width) = 30
⇒ 2l + 2 × width = 30
⇒ 2 × width = 30 - 2l
⇒ width =
= (15-l) feet,
Now, area of the rectangle,
A = length × width
= l × (15-l)
= 15l - l²
Which is the required polynomial expression.
Note :
Polynomial expression : an expression having terms consisting coefficients and variables separated by addition, subtraction and multiplication.
Answer:
False
Step-by-step explanation:
2*2 =4, so if this were true 4*2 would equal 6. Since it doesn't, the answer is false.
I hope this helps :)
1 Answer:
10 pound of sugar
Step-by-step explanation:
So you have 6x-30. The only factor I can think of for this is x+5. Because you have 6(x+5)= 6x+30
Your question is: The perimeter of a rectangle is 60 meters. What are the possible lengths of any of the rectangle’s sides if its area exceeds 216 square meters?
The answer would be (12,18)
