Mathematics

Answer:

Adding and Subtracting Polynomials. When adding and subtracting polynomials , you can use the distributive property to add or subtract the coefficients of like terms. Use the commutative property to group like terms. (Recall that "like terms" are monomials with the same variables, such as 3 x 2 y and 82 x 2 y .)

Please help ill give whoever answers the best the brainliest answer :)
lawyer [7]

Answer: The first answer choice

Step-by-step explanation:

In the first answer choice, the distance increases for two units, then decreases for three units. The distance then increased for 4 units, stayed level for 3 units, and then decrease slowly for 6 units. The graph exactly follows this trend.

The second answer is <em>immediately wrong</em> because it relates the distance between the car and the concert venue. <em>It never mentioned that the car moved, and the venue obviously can't move</em>.

The third answer says that after the first increase/decrease, Tyler went to go text his friends. However, <em>the graph does not show a flat area after the first increase/decrease</em>.

The fourth answer, like the second answer is immediately wrong because <em>homes and schools can't move</em>.

This is my first response, so I hope it was helpful. :D

Use the expression below:
skelet666 [1.2K]

Answer:

Part A: 8b -12c -16

Part B: 4(2b - 3c -4)

Part C: 36

Step-by-step explanation:

Part A:

5b + 3c - 20 + 3b - 15c + 4

= 8b -12c -16

Part B:

Factorising 8b -12c -16

= 4(2b - 3c -4)

Part C:

= 4[2(2)-3(-3)-4)]

= 4[4+9-4]

= 4[9]

= 36
