A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

Can you find the perimeter if you know area of a rectangle?

You can find the perimeter of a rectangle if you know its area and the length of one side. Divide the area by the length of the known side and the quotient will be the length of a side perpendicular to the known side, and then multiply the sum of the two sides by two to find the perimeter.


What is the perimeter of a rectangle with one side 9cm if area is 27cm?

24 cm is.


How do you write simplified expressions for the area and the perimeter of a rectangle one side 3a other side 5b?

Area: 15ab Perimeter: 2(3a+5b) or as 6a+10b


Can you find the area of a rectangle only knowing the perimeter?

To find the area of a rectangle, you multiply the length by the width (one side by a different side) Or you could count how many centimeter squares make up the rectangle


Area of 18 perimeter of 28?

Infinitely many shapes have a perimeter of 28 and an area of 18. A rectangle that has those qualities has one side about 1.432 and the other about 12.568


A rectangle has a perimeter of 10 ft Write the area A of the rectangle as a function of the length of one side x of the rectangle?

This question has no unique answer. A (3 x 2) rectangle has a perimeter = 10, its area = 6 A (4 x 1) rectangle also has a perimeter = 10, but its area = 4 A (4.5 x 0.5) rectangle also has a perimeter = 10, but its area = 2.25. The greatest possible area for a rectangle with perimeter=10 occurs if the rectangle is a square, with all sides = 2.5. Then the area = 6.25. You can keep the same perimeter = 10 and make the area anything you want between zero and 6.25, by picking different lengths and widths, just as long as (length+width)=5.


What is the perimeter of a rectangle with one side 5cm if it has an area of 35cm2?

Area = 35 cm2 and one side = 5 cm => other side = 7 cm So perimeter = 2(5 + 7) = 2*12 = 24 cm


How can you draw a rectangle that has an area of 24 and a perimeter of 22?

One side 8 long, other side 3 long.


Is length of the rectangle and the perimeter are the same?

No. The length is the measurement of the distance from the bottom to the top of the rectangle, or from one side to the other side. The perimeter is the distance all the way around the rectangle.


What is the greatest perimeter of a rectangle with integer side lengths and an area of 2014 sq cm?

For any given area, the rectangle closest to a square will have the smallest perimeter; and the one that is most "stretched out" has the largest perimeter. In this case, that would be a width of 1 and a length of 2014.


How do you find the perimeter using area?

Perimeter and area have a relationship but the shape of the space and area together determine the perimeter. A circle has the maximum Area for a given perimeter -or- the minimum perimeter for a given area. Area = pi * radius * radius and perimeter = 2*pi * radius for a circle; perimeter = 2* pi * square root of (Area/pi) With regards to square and rectangles the closer a shape is to square the greater the Area for a given perimeter -or- the minimum the perimeter to a given area. Square Area = side * side and periemter = 4 * side So perimeter = 4 * square root (Area) To solve for a rectangle, you must know ONE side to solve as the relationship between the Area and the perimeter is change as the relative size of side1 and side 2 changes. Rectangle Area = side1 * side2 and perimeter = 2 * (side1 + side2) so perimeter = 2 * (Area/side1 + side1) or 2 * (Area/side2 + side2)


Can you calculate the area if you have the perimeter and one side?

Only if you have one additional piece of information, such as that it is a rectangle or a triangle, or that all sides are equal.
