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

What is the difference between an area and perimeter?

area is................ length x width perimeter is .......... length x width x length x width * * * * * WRONG. Area is the amount of space occupied by a shape. In the case of a rectangle, it is length x width, as stated above. But that does not work for circles, ellipses, triangles, other quadrilaterals and polygons and many other shapes, all of which have areas. A perimeter is the sum of all the lengths bordering the shape. The perimeter of a rectangle is NOT length x width x length x width but their sum! But again, that does not work for most other shapes.


How do you determine area with length and width?

Multiply the length by the width, and you will get your area. For example... a standard piece of paper has two long sides, and two short sides. The two short sides are exactly the same length, and the two long sides are exactly the same length. The length of a long side is 11 inches and the length of a short side is 8.5 inches. To find the area you would multiply 11x8.5 which equals 93.5. Your area would then be 93.5 square inches. The equation is l*w=a l being length w being width a being area this equation will work for any squares or rectangles!


How do you work out a square prism width and height when given volume and length?

Volume = Length x Width x Height. If the prism is square, then either Height = Width or Height = Length In the first case, Volume = Length x Width2 and so Width = sqrt(Volume/Length) and Height = Width. In the second case, Volume = Length2 x Width and so Width = Volume/Length2 and Height = Length.


What is the perimeter of a rectangle which has a diagonal of 8.50 cm and an area of 3000 square mm showing work with answer?

Here is what you are supposed to do: * Convert to consistent units. For example, convert the cm to mm. * Write an equation for the diagonal (in terms of length and width). Replace the known diagonal. * Write an equation for the area, in terms of length and width. * Solve the two equations simultaneously. * Calculate the perimeter.


Is area of a 7 by 8 rectangle?

To work out the area of a rectangle you simply multiply the width by the length:Here the width and length are 7 and 8 so by multiplying them together you get:56Remember, that if units are involved such as centimetres, you must write a squared sign after the digits. For example if it were 7cm and 8cm, you would write the answer as 56cm2

How do you find the width of a rectangle if you know its length and its area?

If you pretend that the width is X .Then you'll know that X times length = area. So if you say the length is 5 ,then the area is 10 the X must be 2 so the width is 2you simply work out what times the length makes the area.
