Liliana wants to write an equivalent expression for n + 3 minus 5 n + 6. Which of her attempts uses the algebraic properties correctly?

Commutative property: n minus 5 n + 3 + 6. Associative property: (1 n minus 5 n) + (3 + 6). Distributive property: (1 minus 5) n + (3 + 6). Addition property: negative 4 n + 9.

Associative property: n minus 5 n + 3 + 6. Commutative property: (1 n minus 5 n) + (3 + 6). Distributive property: (1 minus 5) n + (3 + 6). Addition property: negative 4 n + 9.

Addition property: n minus 5 n + 3 + 6. Associative property: (1 n minus 5 n) + (3 + 6). Distributive property (1 minus 5) n + (3 + 6). Commutative property: negative 4 n + 9.

Commutative property: n minus 5 n + 3 + 6. Distributive property: (1 n minus 5 n) + (3 + 6). Associative property: (1 minus 5) n + (3 + 6). Addition property: negative 4 n + 9.

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.

its a, i had the same answer, its from study island right
