What is the perimeter of a rectangle with a length of 23 mm and a width of 26
mm?
Perimeter of a Rectangle
P = 21+ 2w or P = 2(1 + w)
Perimeter of a Square
P = 45
O A) 49 mm
OB) 98 mm
OC) 184 mm
OD 598 mm

really really sorry if i'm

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
