Answer:

Step-by-step explanation:

If 10 + 5x is 12 more than 8, what is the value of 3x? We can represent this with the equation below.

10+5x = 12+8.

Simplifying this gives us 10+5x = 20, then 5x = 10, then x = 2.

If x = 2, then 3x = 6.

Answer:

3x=6

Step-by-step explanation:

10 + 5x =8+12

10 +5x = 20

Subtract 10 from each side

10-10+5x=20-10

5x= 10

Divide by 5

5x/5 = 10/5

x = 2

We want 3x

3(2) = 6

3x=6

valentinak56 [21]

Answer:

A quadratic Trinomial

Step-by-step explanation:

hope this helps

Given

(3x² - 11x - 4) - (2x² - x - 6)

Distribute both parenthesis, noting the second is distributed by - 1

= 3x² - 11x - 4 - 2x² + x + 6 ← collect like terms

= x² - 10x + 2 ← this is a quadratic with 3 terms, thus trinomial → A
