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 perimeter of a rectangle 7 in by 2 in enlarged by the scale factor of 1.5?

A rectangle 10.5 x 3 will have a perimeter of 27 in.

What happens to the perimeter when a rectangle is enlarged by a scale factor of 3?

It will be three times the size. Each length will be multiplied by 3.. Perimeter = h+h+w+w if we multiply each by three then we get 3h+3H+3w+3w = 3P

How does scale factor relate to perimeter?

Scale factor and perimeter are related because if the scale factor is 2, then the perimeter will be doubled. So whatever the scale factor is, that is how many times the perimeter will be enlarged.

How do you enlarge a rectangle by 2.5 with scale factor?

If you assume that 2.5 refers to the scale factor, you multiply each linear measurement by 2.5. This includes the width, the length, and - if you want to use it to construct your new rectangle - the diagonals. It also happens to include the perimeter, but you probably won't need that to construct the rectangle.

How do you find the ratio of the perimeter of two similar rectangles?

The ratio of the perimeters is equal to the scale factor. If rectangle #1 has sides L and W, then the perimeter is 2*L1 + 2*W1 = 2*(L1 + W1).If rectangle # 2 is similar to #1 and sides are scaled by a factor S, so that L2 = S*L1 and W2 = S*W1, the perimeter of rectangle #2 is 2*(L2 + W2)= 2*(S*L1 + S*W1) = S*2*(L1 + W1) = S*(perimeter of rectangle #1).

What happens to an enlarged image when the scale factor of enlargement is greater than one?

It depends on the aspect ratio. If it is a square object then it should scale up evenly. But if it is a rectangle then eventually a large enough scale factor will make it looked stretch on the longer sides.

What happens to an enlarged image when the scale factor of enlargement is one?

Absolutely nothing. A scale factor of 1 is the same as saying do not change the scale.

The area of a rectangle is 36 sq inches. Which of these is not a possible perimeter 40 in 36 in 26 in 18 in?

18" is not a possible perimeter measurement. Assume the dimensions of the rectangle are so close to those of a square that the difference can be disregarded. This is the condition when the perimeter is at its minimum. When the rectangle measures approximately 6" x 6", its area = 36 sq ins, its perimeter = 24" For the area to remain constant then as the length increases by a factor n the width must decrease by that same factor. Area = 6n x 6/n : perimeter = 12n + 12/n :so when n = 1, Perimeter = 12 + 12 = 24 As n increases, say n = 2, Perimeter = 24 + 6 = 30 : And the perimeter continues to increase as the rectangle becomes narrower. Eventually, it will become so narrow that for diagram purposes it will appear as a straight line.
