The expression to find the perimeter of a rectangle is 2(length + width). What is the perimeter, in units, of a rectangle of len

harina [27]

Answer:

OPTION B

$1\frac{2}{7}units$

Step-by-step explanation:

1. You have the following formula for calculate the perimeter of a rectangle:

$P=2(l+w)$

Where l is the lenght and w i the width.

2. Therefore, if the rectangle has the following dimensions:

$l=\frac{1}{7}units\\\\w=\frac{1}{2}units$

You can substitute these values into the formula shown above to calculate the perimeter of a rectangle. Therefore, you obtain the following result:

$P=2(\frac{1}{7}units+\frac{1}{2}units)=\frac{9}{7}units$ or $1\frac{2}{7}units$

Find the LCM of these two expressions: m2 + 11m + 10 and m2 + 9m – 10.

marissa [1.9K]

Answer:

(m-1)(m+1)(m+10)

Step-by-step explanation:

Factors of each expression:

m² + 11m + 10 =
m²+m + 10m+10 =
m(m+1)+10(m+1) =
(m+1)(m+10)

m² + 11m + 10 = (m+1)(m+10)

m² + 9m – 10 =
m² - m + 10m - 10 =
m(m-1) + 10(m-1) =
(m-1)(m+10)

m² + 9m – 10 = (m-1)(m+10)

LCM of the two expressions is:

(m-1)(m+1)(m+10)
